1000BASE-X SFP Ports SFP (Small Form Factor Pluggable) ports support fiber Gigabit Ethernet short-wave (SX), long-wave (LX), long-haul (LH70) and copper (T) SFP Transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and remote 1000 Mbps workgroups or to create a high capacity aggregated link backbone connection. The default state for these ports is auto-negotiation enabled, where the speed, duplex and flow control modes are negotiated. As the speed and duplex modes are fixed by the media type, only the flow control is negotiated with the link partner. Alternatively, auto-negotiation can be disabled (except 1000BASE-T which auto-neogtiation is mandatory) and the flow control setting can be manually configured. Console Port The console port allows you to connect a terminal and perform remote or local out-of-band management. As the console port on the Switch is an RJ-45 port, you will need to connect an RJ-45 to DB9 converter cable to a standard null modem cable in order to connect a terminal. Unit LED The Unit LED is a seven segment display visible on the front of the Switch. The Unit LED can be used to indicate the unit number in a fabric, POST test ID and software upgrade information. In the unlikely event of a hardware fault occurring, the Unit LED may be used to help diagnose the problem. For information on using the Unit LED for problem solving, see “Solving Problems Indicated by LEDs” on page 62 LEDs Table 4 lists LEDs visible on the front of the Switch, and how to read their status.

25 Connecting a Redundant Power Supply The Switch 5500 has an unearthed 48V DC Redundant Power Supply socket. WARNING: The installation of the Redundant Power Supply (RPS) should only be carried out by properly trained and qualified personnel. WARNING: These instructions must be read in conjunction with the RPS flyer and the safety and installation instructions supplied with your RPS. WARNING: When powering any Switch 5500 from an RPS, the unit must be earthed (grounded). This can be achieved by either connecting the power cord to the unit or by connecting the earth terminal on the rear of the unit to a reliable electrical earth, or by connecting both. You must ensure that the earth connection is made before connecting the DC supply from the RPS. WARNING: Any RPS must be approved as an unearthed SELV output in accordance with IEC 60950-1/UL 60950-1/EN 60950-1. WARNING: The characteristics of the Switch 5500 DC supply input are given in Appendix C on page 105. The Switch 5500 can be powered in three different ways: ■ AC Mains only — does not offer any power redundancy. If the AC mains supply or the AC power supply fail, the Switch will power off. ■ AC Mains and Unearthed 48V DC (primary supply) — the internal AC supply acts as the backup in the event of a DC power failure. ■ DC only — the Switch does not need an AC supply and the resiliency is provided by the DC supply. This is useful in an environment where only DC power is available. The RPS provides two main benefits to the customer: ■ Power Redundancy — if a Switch is powered from the mains supply unit, a failure of the internal power supply will cause the Switch to fail. This can be overcome by connecting both the AC and DC RPS supplies to the Switch. Additional redundancy can also be added to the DC power by using (N+1) DC power supplies to further increase the availability of the system. ■ Uninterruptible Power — the system allows easy connection and maintenance of batteries to the RPS shelf to further increase the availability of the system. DUA1715-0AAA02.book Page 25 Wednesday, March 23, 2005 11:17 AM

Table 6 below, outlines the behavior of the Switch when changes occur to the power system, such as removing the AC mains cable when the RPS is attached. The responses to the different power inputs are controlled by the Switch’s internal power supply and not by the RPS. Table 6 Switch Power Inputs 3Com’s RPS solution uses 48V DC power distribution. The RPS system provides bulk 48V DC power that is separately distributed to a number of network switches. Each RPS consists of a shelf which can house from one to six rectifiers, a Distribution Module and a Management Module. The RPS generates 48V DC power using power supply units (or rectifiers). The outputs of the rectifier(s) are connected together so that the total 48V power available can be increased by adding additional rectifiers. For example, three 1500W rectifiers can provide up to 4500W. Hot removal or insertion of a rectifier will not affect the 48V DC output voltage. Table 7 shows an example of the total power available from a number of 1500W rectifiers. A minimum of two rectifiers are required for each shelf to provide N+1 rectifier redundancy.

27 Table 7 Power Availability The unearthed 48V DC power distribution provides the mechanism to connect to the Switch 5500. The distribution consists of a number of circuit breakers and connection terminals for the positive (common) and negative 48V outputs. Each Switch 5500 must be individually connected to a circuit breaker terminal. A battery can also be connected to battery terminals prior to the DC power distribution to provide uninterrupted power in order to protect against the loss of AC mains power. Specifying the Redundant Power System For an approved vendor list, more details about purchasing the RPS and a full set of requirements go to: http://www.3Com.com/RPS 3Com’s redundant power solution allows the use of any off-the-shelf 48V DC RPS that provides an ‘unearthed SELV’ output in compliance with IEC 60950-1/UL 60950-1/EN 60950-1, as defined in Appendix C on page 105. Connecting the Switch to the Redundant Power System When connecting the RPS to the Switch, the circuit breaker and 2-core cable need to be matched to the power rating of the Switch. Table 8 shows the recommended circuit breaker and cable rating for the Switch 5500. The recommended cable length should not exceed 3 metres (9.84 feet).

Connecting the Earthing Cable Use the earthing cable that accompanies your Switch if the length is suitable, alternatively use the earthing cable specification as defined in Appendix C on page 105. The recommended cable length should not exceed 3 metres (9.84 feet). WARNING: RPS Manufacturers recommendations must be followed when connecting the cable to the RPS. WARNING: Ensure that the circuit breaker in the RPS is in the open (off) position when connecting the cable to the RPS. WARNING: You must ensure that the positive terminal on the Switch is connected to the positive (common) terminal of the RPS and that the negative terminal on the Switch is connected to the negative (circuit breaker) terminal of the RPS. WARNING: Ensure that the circuit breaker in the RPS is in the open (off) position when connecting the RPS cable and connector to the Switch. Figure 5 shows how to connect the power supply to the RPS socket in the back of the Switch. Use the cable tie supplied with your Switch to support the cable at the rear of the RPS connector as shown.

Placing Units On Top of Each Other If the Switch units are free-standing, up to eight units can be placed one on top of the other. If you are mixing a variety of SuperStack® units, the smaller units must be positioned at the top. If you are placing Switch units one on top of the other, you must use the self-adhesive rubber feet supplied. Apply the feet to the underside of each Switch, sticking one in the marked area at each corner. Place the Switch units on top of each other, ensuring that the feet of the upper unit sit fully on the lower unit. The Power-up Sequence The following sections describe how to get your Switch 5500 powered-up and ready for operation. Powering-up the Switch 5500 Use the following sequence of steps to power-up the Switch. 1 Plug the power cord into the power socket at the rear of the Switch. 2 Plug the other end of the power cord into your power outlet. The Switch powers-up and runs through its Power On Self Test (POST), which takes approximately one minute. Checking for Correct Operation of LEDs During the Power On Self Test, all ports on the Switch are disabled and the LEDs light. The PWR LED will flash green during the POST. When the POST has completed, check the PWR LED to make sure that your Switch is operating correctly. Table 10 shows possible colors for the LED. Table 10 PWR LED Colors Color State Green The Switch is powered-up and operating normally. Red The Switch has failed its Power On Self Test (POST). Yellow flashing Some ports have failed POST* * In this event you can still use the Switch via the remaining ports that have passed the POST. Off The Switch is not receiving power.

LEDs” on page 62 for a list of suggested solutions. CAUTION: The Switch has no ON/OFF switch; the only method of connecting or disconnecting mains power is by connecting or disconnecting the power cord. SFP Operation The following section describes how to insert an SFP transceiver into an SFP port. SFP transceivers are hot-insertable and hot-swappable. You can remove them from and insert them into any SFP port without having to power down the Switch. You will need to install an SFP transceiver if you wish to create an XRN Distributed Fabric as an SFP port is used to interconnect the Switches. Approved SFP Transceivers The following list of approved Gigabit Ethernet SFP transceivers is correct at the time of publication. ■ 3CSFP91 SFP (1000BASE-SX) ■ 3CSFP92 SFP (1000BASE-LX) ■ 3CSFP97 SFP (1000BASE-LH70) ■ 3CSFP93 SFP (1000BASE-T) To access the latest list of approved SFP transceivers for the Switch on the 3Com Corporation World Wide Web site, enter this URL into your internet browser: http://www.3com.com Inserting an SFP Transceiver To be recognized as valid, the SFP transceiver must have the following characteristics: ■ 1000BASE-SX SFP transceiver Use this transceiver to connect Gigabit Ethernet SFP ports on the Switch directly to a multi-mode fiber-optic cable. ■ 1000BASE-LX SFP transceiver DUA1715-0AAA02.book Page 31 Wednesday, March 23, 2005 11:17 AM

Use this transceiver to connect Gigabit Ethernet SFP ports on the Switch directly to a single-mode fiber-optic cable or to multimode fiber using a conditioned launch cable. ■ 1000BASE-LH70 SFP transceiver Use this transceiver to connect Gigabit Ethernet SFP ports on the Switch directly to a single-mode fiber-optic cable. ■ 1000BASE-T SFP transceiver This transceiver uses Category 5 copper cabling with RJ-45 connectors and supports segment lengths of up to 100 m (328 ft). If the SFP transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 63. 3Com recommends that you only use SFPs supplied by 3Com. If the SFP transceiver is invalid it will not be recognized by the Switch. Use the following sequence of steps to activate the SFP ports: 1 The SFP transceiver is keyed and there is only one way in which it can be installed correctly. It is not necessary to power-down your Switch. 2 Hold the transceiver so that the connector is toward you and the product label is visible. Ensure the wire release lever is closed (in the upright position). 3 Gently slide the transceiver into the SFP port until it clicks. If the transceiver does not click into place, remove it, turn it over and re-insert. 4 Remove the plastic protective cover if fitted. Figure 6 Inserting an SFP Transceiver DUA1715-0AAA02.book Page 32 Wednesday, March 23, 2005 11:17 AM

33 5 Use an appropriate cable to connect the transceiver to a suitable device. 6 Check the LEDs on the front of the Switch to ensure that it is operating correctly. Refer to “LEDs” on page 16 for more information. Removing an SFP Transceiver If you wish to remove the transceiver (it is not necessary to power-down your Switch): 1 Disconnect the cable from the transceiver. 2 Move the wire release lever downwards until it is pointing toward you. 3 Pull the wire release lever toward you to release the catch mechanism; the transceiver will then easily slide out. Choosing the Correct Cables All of the ports on the Switch are Auto-MDIX, that is they have a cross-over capability. These ports can automatically detect whether to operate in MDI or MDIX mode. Therefore you can make a connection to one of the ports with a straight-through (MDI) or a cross-over cable (MDIX). The Auto-MDIX feature only operates when auto-negotiation is enabled. If auto-negotiation is disabled, all the Switch ports are configured as MDIX (cross-over). If you want to make a connection to another MDIX port, you need a cross-over cable. Many ports on workstations and servers are configured as MDI (straight-through). If you want to make a connection to an MDI port, you need to use a standard straight-through cable. See Table 11. Product label Suitable port on host Switch DUA1715-0AAA02.book Page 33 Wednesday, March 23, 2005 11:17 AM

3Com recommends that you use at least Category 5 twisted pair cable — the maximum segment length for this type of cable is 100 m (328 ft.). Table 11 Cables required to connect the Switch to other devices if auto-negotiation is disabled CAUTION: If you want to install the Switch using a Category 5E or Category 6 cable, 3Com recommends that you briefly connect the cable to a grounded port before connecting network equipment. If you do not, the cable’s Electrostatic Discharge (ESD) may damage the Switch's port. You can create a grounded port by connecting all wires at one end of a UTP cable to an earth ground point, and the other end to a female RJ-45 connector located, for example, on a Switch rack or patch panel. The RJ-45 connector is now a grounded port. 3Com recommends that you use Category 5 twisted pair cable — the maximum segment length for this type of cable is 100 m (328 ft).

To make full use of the features offered by your Switch, and to change and monitor the way it works, you have to access the management software that resides on the Switch. This is known as managing the Switch. Managing the Switch can help you to improve the efficiency of the Switch and therefore the overall performance of your network. This chapter explains the initial set up of the Switch and the different methods of accessing the management software to manage a Switch. It covers the following topics: ■ Methods of Managing a Switch ■ Setting Up Overview ■ Manually Configuring IP Information ■ Viewing Automatically Configured IP Information ■ Setting Up Command Line Interface Management ■ Setting Up Command Line Interface Management using SSH ■ Setting Up Web Interface Management ■ Setting Up SNMP Management V1 or V2 ■ Default Users and Passwords ■ Configuration Conversion Utility DUA1715-0AAA02.book Page 29 Wednesday, March 23, 2005 11:17 AM

Methods of Managing a Switch To manage your Switch you can use one of the following methods: ■ Command line interface management ■ Command line interface management using SSH ■ Web interface management ■ SNMP management Command Line Interface Management Each Switch has a command line interface (CLI) that allows you to manage the Switch from a workstation, either locally via a console port connection (see Figure 7), or remotely over the network (see Figure 8). Figure 7 CLI Management via the Console Port Figure 8 CLI Management over the Network Refer to “Setting Up Command Line Interface Management” on page 44. There are two main views in the CLI: User View — this view is shown when you first connect to the Switch and shows basic information about operation and statistics. The prompt for user view is (where xx is either SI or EI). System View — this view enables you to configure the system parameters. To display this view, from user view enter system-view. The prompt for system view is [SW5500-XX].

31 Command Line Interface Management using SSH The Switch 5500 supports Secure Shell version 1.5 (SSHv1.5), allowing secure access to the Command Line Interface of the Switch. If you use SSH to administer your Switch and the network traffic is intercepted, no passwords or configuration information will be visible in the data. To securely administer the Switch using the Command Line Interface you need a third party SSH client. Web Interface Management Each Switch has an internal set of web pages that allow you to manage the Switch using a Web browser remotely over an IP network (see Figure 9). Figure 9 Web Interface Management over the Network Refer to “Setting Up Web Interface Management” on page 46. SNMP Management You can manage a Switch using any network management workstation running the Simple Network Management Protocol (SNMP) as shown in Figure 10. For example, you can use the 3Com Network Director software, available from the 3Com website. Figure 10 SNMP Management over the Network Refer to “Setting Up SNMP Management V1 or V2” on page 47.

Setting Up Overview This section gives an overview of what you need to do to get your Switch set up and ready for management when it is in its default state. The whole setup process is summarized in Figure 11. Detailed procedural steps are contained in the sections that follow. In brief, you need to: ■ Configure IP information manually for your Switch or view the automatically configured IP information ■ Prepare for your chosen method of management Figure 11 Initial Switch Setup and Management Flow Diagram Plug and Play Setup Initial IP Information Setup Feature Management Power Up the Switch. IP Information is automatically configured via DHCP See page 33 Do you want to manually configure the IP information? Connect to the con- sole port and use the Command Line Inter- face. See page 35 How do you want to manage your Switch? See SNMP See page 47 Command Line Interface Connect via the console port. See page 44 Web Interface Connect over the network via Telnet. See page 44 Connect over the network. See page 47 How do you want to view the automatically configured IP information? How do you want to connect to the Switch? Connect to a front panel port and use the Web Interface or Command Line Interface. See page 35 Use 3Com Network Director (3ND). See page 42 Connect to the console port and use the Command Line Interface. See page 42 Yes No DUA1715-0AAA02.book Page 32 Wednesday, March 23, 2005 11:17 AM

33 CAUTION: To protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Switch. For more information on default users and changing default passwords, see “Default Users and Passwords” on page 48. IP Configuration You can use one of the following methods to allocate IP information to your Switch (essential if you wish to manage your Switch across the network). Manual IP Configuration When you configure the IP information, the Switch remembers the information that you enter until you change it again. You should use the Manual IP configuration method if: ■ you do not have a DHCP or BootP server on your network, or ■ you want to remove the risk of the IP address ever changing, or ■ your DHCP or BootP server does not allow you to allocate static IP addresses. (Static IP addresses are necessary to ensure that the Switch is always allocated the same IP information.) For most installations, 3Com recommends that you configure the Switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP or BootP server, and eliminates the risk of the IP address changing. To manually enter IP information for your Switch, work through the “Manually Configuring IP Information” section on page 35. Automatic IP Configuration via DHCP By default the Switch tries to configure itself with IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network. When using automatic IP configuration it is important that the IP address of the Switch is static, otherwise you will not know what the IP address is and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the Switch. Refer to the documentation that accompanies your DHCP server. DUA1715-0AAA02.book Page 33 Wednesday, March 23, 2005 11:17 AM

For a detailed description of how automatic IP configuration operates, please refer to the Configuration Guide on the CD-ROM that accompanies your Switch or the 3Com Web Site. You should use the automatic IP configuration method if: ■ your network uses DHCP to allocate IP information, or ■ flexibility is needed. If the Switch is deployed onto a different subnet, it will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the Switch. If the Switch is not allocated with an automatic IP addresss, the IP configuration will be blank or shown as ‘’’’. If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the “Viewing Automatically Configured IP Information” section on page 41. Preparing for Management Once your Switch’s initial set up is complete you can set up your chosen management method as described in “Methods of Managing a Switch” on page 30. For detailed information about the specific web interface operations and command line interface commands and problem solving, refer to the “SuperStack 4 Switch Command Reference Guide” on the CD-ROM that is supplied with the Switch or on the 3Com Web site. DUA1715-0AAA02.book Page 34 Wednesday, March 23, 2005 11:17 AM

35 Manually Configuring IP Information You can manually configure the Switch IP information in the following ways: ■ Connecting to the console port — connect a workstation using a console cable to the console port of the Switch. You can then manually enter IP information using the command line interface (CLI). ■ Connecting to a front panel port — connect a workstation using an Ethernet cable to a front panel port of the Switch. You can then manually enter IP information using the web interface or the command line interface (CLI). Connecting to the Console Port To set up your Switch manually you can make a connection to the console port, (this example describes a local connection to the console port, rather than one via a modem). You can do this whilst the Switch is offline, that is, before you connect the Switch to a network, or whilst the Switch is online, that is, connected to a network. Pre-requisites ■ A workstation with terminal emulation software installed, such as Microsoft Hyperterminal. This software allows you to communicate with the Switch via the console port directly. ■ Documentation supplied with the terminal emulation software. ■ The console cable (RJ-45) supplied with your Switch. You can find pin-out diagrams for the cable in Appendix B on page 101. ■ You need to have the following so that you can manually set up the Switch with IP information: ■ IP address ■ subnet mask ■ default gateway ■ management VLAN ID, normally set to the default value (1) DUA1715-0AAA02.book Page 35 Wednesday, March 23, 2005 11:17 AM

Connecting the Workstation to the Switch 1 Connect the workstation to the console port using the console cable as shown in Figure 12.

The initial set up of your Switch is now complete and the Switch is ready for you to set up your chosen management method. See “Methods of Managing a Switch” on page 30. Viewing Automatically Configured IP Information If you allow the Switch to automatically configure its own IP information you need to discover and view the IP information before you can begin to manage the Switch. You can discover the IP information in two ways: ■ Using 3Com Network Director — this application will auto-discover the Switch and display the automatically allocated IP information assigned to the Switch. DUA1715-0AAA02.book Page 41 Wednesday, March 23, 2005 11:17 AM

■ Connecting to the Console Port — connect a workstation using a console cable to the console port of the Switch. You can then view the IP information automatically assigned to the Switch using the command line interface (CLI). Using 3Com Network Director You can use the 3Com Network Director application (available from the 3Com website) to discover the automatically allocated IP information. 1 Connect your Switch to the network. 2 Power-up the Switch and wait for two minutes. 3 Launch 3Com Network Director and run the Auto-discovery wizard. 3Com Network Director will auto-discover the new Switch and display the IP information that has been automatically allocated to the Switch. Most DHCP and BootP servers allow static IP addresses to be configured so that you know what IP address the Switch will be given. Refer to the documentation that accompanies your DHCP or BootP server. If your network does not have a DHCP or BootP server, the workstation running 3Com Network Director must be on the same subnet as the Switch, because Auto-IP addresses are non-routable. Connecting to the Console Port Alternatively, you can view the automatically configured IP information via the command line interface (CLI) through a connection to the console port. (This example describes a local connection to the console port, rather than a remote one via a modem.) For further information on connecting via the console port see “Connecting the Workstation to the Switch”on page 36. Viewing IP Information via the Console Port You are now ready to view the automatically allocated IP information using the command line interface. 1 Connect your Switch to the network using the Ethernet cable. As soon as a network connection is made the Switch begins the automatic IP configuration process. The automatic IP configuration process usually completes within one minute. 2 The command line interface login sequence begins as soon as the Switch detects a connection to its console port.

Setting Up Command Line Interface Management This section describes how you can set up command line interface management using a local console port connection or over the network. User Interface Overview User interface configuration is provided by the Switch to configure and manage the port data. There are two types of user interfaces: AUX User Interface — used to log in to your Switch via the console port. A fabric can have up to eight AUX user interfaces. VTY User Interface — used to Telnet to the Switch. The Switch can have up to five VTY user interfaces. CLI Management via the Console Port To manage a Switch using the command line interface via the local console port connection: 1 Ensure you have connected your workstation to the console port correctly as described in “Connecting to the Console Port” on page 35. 2 Your Switch is now ready to continue being managed and/or configured through the CLI via its console port. CLI Management over the Network To manage a Switch using the command line interface over a network using Telnet: 1 Ensure you have already set up the Switch with IP information as described in “Methods of Managing a Switch” on page 30. 2 Check that you have the IP protocol correctly installed on your management workstation. You can check this by trying to browse the World Wide Web. If you can browse, the IP protocol is installed. 3 Check you can communicate with the Switch by entering a ping command at the DOS prompt in the following format: c:\ ping xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the IP address of the Switch) If you get an error message, check that your IP information has been entered correctly and the Switch is powered up. 4 To open a Telnet session via the DOS prompt, enter the IP address of the Switch that you wish to manage in the following format: >telnet xxx.xxx.xxx.xxx DUA1715-0AAA02.book Page 44 Wednesday, March 23, 2005 11:17 AM

45 (where xxx.xxx.xxx.xxx is the IP address of the Switch) If opening a Telnet session via third party software you will need to enter the IP address in the format suitable for that software. 5 At the login and password prompts, enter admin as your user name and press Return at the password prompt (or the password of your choice if you have already modified the default passwords). If the login prompt does not display immediately, press Return a few times until it starts. 6 If you have logged on correctly, the Switch you wish to manage is displayed as <5500-xx> (where xx is either SI or EI, as shown in Figure 13 on page 37). Setting Up Command Line Interface Management using SSH This section describes how you can set up Command Line Interface management using SSH over a network. To manage a Switch using the command line interface over a network using SSH: 1 Ensure you have already set up the Switch with IP information as described in “Methods of Managing a Switch” on page 30. 2 Check that you have the IP protocol correctly installed on your management workstation. You can check this by trying to browse the World Wide Web. If you can browse, the IP protocol is installed. 3 Check you can communicate with the Switch by entering a ping command at the DOS prompt in the following format: c:\ ping xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the IP address of the Switch) If you get an error message, check that your IP information has been entered correctly and the Switch is powered up. The switch automatically generates a host key pair when it is powered up for the first time, or after any reset to factory defaults. Host key generation may take a while, during which time SSH connections to the switch will be refused. 4 Install an SSH client application on the workstation you want to use to access the switch. 3Com recommends the following SSH clients; PuTTY, OpenSSH and SSH Communications Security Corp Secure Shell. DUA1715-0AAA02.book Page 45 Wednesday, March 23, 2005 11:17 AM

5 Open an SSH session and access the Switch using the Switch’s IP address and port number. The first time you connect to the switch the client will ask you to confirm that the host key is correct for the device. 6 The Switch and the SSH client will authenticate each other and a secure connection will be established. 7 Enter your usual username and password to access the CLI commands. For increased security please change the default password when using SSH for the first time. For further information on generating a host key on your switch and transferring keys to the Switch using TFTP server please refer to the Configuration Guide that is supplied with your Switch. Setting Up Web Interface Management This section describes how you can set up web interface management over the network. Pre-requisites ■ Ensure you have already set up the Switch with IP information as described in “Methods of Managing a Switch” on page 30. ■ Ensure that the Switch is connected to the network using a Category 5 twisted pair Ethernet cable with RJ-45 connectors. ■ A suitable Web browser. Choosing a Browser To display the web interface correctly, use one of the following Web browser and platform combinations: Table 12 Supported Web Browsers and Platforms Windows 2000 Windows XP Windows Server 2003 Red Hat Linux 9 Solaris 7/9 Netscape 7.1 ✓ ✓ ✕ ✕ ✓ Internet Explorer 5.5 ✓ ✓ ✓ ✕ ✕ Internet Explorer 6.0 ✓ ✓ ✓ ✕ ✕ Mozilla 1.4 ✕ ✕ ✕ ✓ ✓ DUA1715-0AAA02.book Page 46 Wednesday, March 23, 2005 11:17 AM

47 For the browser to operate the web interface correctly, JavaScript™ and Cascading Style Sheets must be enabled on your browser. These features are enabled on a browser by default. You will only need to enable them if you have changed your browser settings. Web Management Over the Network To manage a Switch using the web interface over an IP network: 1 Check that you have the IP protocol correctly installed on your management workstation. You can check this by trying to browse the World Wide Web. If you can browse, the IP protocol is installed. 2 Check you can communicate with the Switch by entering a ping command at the DOS prompt in the following format: c:\ ping xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the IP address of the Switch) If you get an error message, check that your IP information has been entered correctly and the Switch is powered up. 3 Open your web browser and enter the IP address of the Switch that you wish to manage in the URL locator, for example, in the following format: http://xxx.xxx.xxx.xxx 4 At the login and password prompts, enter admin as your user name and press Return at the password prompt (or the password of your choice if you have already modified the default passwords). 5 Click on the Device View button to display the web management options. Setting Up SNMP Management V1 or V2 Any network management application running the Simple Network Management Protocol (SNMP) can manage a Switch if: ■ The correct Management Information Bases (MIBs) are installed on the management workstation. ■ The management workstation is connected to the Switch using a port in VLAN 1 (the Default VLAN). By default, all ports on the Switch are in VLAN 1. You can use the 3Com Network Director application that is available from the 3Com website to provide SNMP management for your Switch. If you use 3Com Network Director it automatically loads the correct MIBs and necessary files onto your workstation. DUA1715-0AAA02.book Page 47 Wednesday, March 23, 2005 11:17 AM

Pre-requisites ■ Documentation supplied with the SNMP network management application software. The default read community string is public. To change this setting in System View, enter display snmp community. The default write community string is private. To change this setting in System View, enter display snmp community. To manage your Switch using an SNMP network management application, you need to specify SNMP community strings for the users defined on the Switch. You can do this using the command line interface system management snmp community command — refer to the command line interface section of the “SuperStack 4 Switch Command Reference Guide” for more information. SNMP V3 is on as default. All commands are in snmp menu in System View. Default Users and Passwords If you intend to manage the Switch using the web interface or the command line interface, or to change the default passwords, you need to log in with a valid user name and password. The Switch has three default user names, and each user name has a different password and level of access. These default users are listed in Table 13. CAUTION: To protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Switch. Table 13 Default Users User Name Default Password Access Level monitor monitor monitor — the user can view all manageable parameters, except special/security features, but cannot change any manageable parameters manager manager manager — the user can access and change the operational parameters but not special/security features admin (no password) security — the user can access and change all manageable parameters DUA1715-0AAA02.book Page 48 Wednesday, March 23, 2005 11:17 AM

49 Use the admin default user name (no password) to login and carry out initial Switch setup. To set a password for the admin user in the CLI, enter the following from system view: [5500-xx]local-user admin [5500-xx-luser-admin]password simple xxxxxxxx (where xxxxxxxx is your chosen password). Save the configuration in the User View. For information on the lost password procedure please refer to the Configuration Guide that is supplied with your Switch. Configuration Conversion Utility The 3Com Switch 5500 Configuration Conversion Utility (CCU) enables you to convert the key configuration parameters from a range of 3Com SuperStack II and SuperStack 3 devices to the configuration file format used by your Switch 5500 unit. The utility provides conversion for a number of Switch features To download the CCU package, select the CCU link on the CD that accompanies your Switch 5500. Alternatively, the CCU download and further information is available at: http://www.3com.com/switchmigration/ DUA1715-0AAA02.book Page 49 Wednesday, March 23, 2005 11:17 AM

FABRIC This chapter contains the information you need to create an XRN Stacking Fabric. It covers the following topics: ■ How To Interconnect Units ■ Guidelines For Interconnecting Units ■ Unit Numbering within the Fabric The procedure for creating a Fabric with the Switch 5500-SI units is the same procedure as that for creating a Fabric with the Switch 5500-EI units. How To Interconnect Units Up to eight 3Com Switch 5500 units can be interconnected to create an XRN Stacking Fabric and then treated as a single manageable unit with one IP address. You can interconnect your Switches to create an XRN Fabric using a standard 1000 Mbps Ethernet connection. Table 14 lists the different variants of the Switch 5500 family, how they physically interconnect and the level of XRN support offered by the Fabric. It is not possible to create a Fabric by interconnecting a 3Com Switch 5500 with any other 3Com device or mix Enhanced Image (EI) Switch 5500 units with Standard Image (SI) units. This section assumes you have either set up your units for management as detailed in Chapter 3 “Setting Up for Management”or that you are using a console cable connected to the console port to set up and allocate IP addresses and so on. 3Com recommends that you do not physically connect the cables on your Fabric ports until you have carried out the initial configuration of the Fabric ports as detailed below. DUA1715-0AAA02.book Page 57 Wednesday, March 23, 2005 11:17 AM

Table 14 SuperStack 4 Switch 5500 Support for XRN Distributed Fabric 1 Ensure that the Switch units that you wish to interconnect have the latest software agent installed. You can use the display version command to check this. 2 Enable the ‘up port’ and the ‘down port’ on each Switch (see Table 14) to operate in Fabric mode using the following CLI command. From the System View enter fabric-port gigabitethernet 1/0/51 enable, for example. As with all Switch 5500 CLI commands, the format for entering a command that is port specific is x/y/z, where x = unit number, y = module number (in the case of the Switch 5500 this will always be 0), z = port number. 3 Connect the Fabric-enabled ‘up’ port on one Switch 5500 unit to the Fabric-enabled ‘down’ port on another Switch 5500 unit using the appropriate connection method for your Switch as detailed in Table 14. 4 To create a fully resilient Fabric: enable the spare Fabric ports on the top-most and bottom-most units in the Fabric as described in the previous steps. Then insert a cable into these two Fabric ports to create a link between the top-most and bottom-most units in the Fabric, as shown in Figure 17 on page 60. This ensures that in the event of a unit failure within the Fabric, the Fabric will continue working and no “Fabric split” will occur. 5 Save all configuration settings. From the User View, enter the save command to save the configuration to your Switch.

59 Guidelines For Interconnecting Units This section offers some guidelines for creating a Fabric. Using these guidelines will help prevent problems arising when setting up your Fabric. ■ The maximum number of Switch units that can be interconnected is eight. ■ It is not possible to create a fabric by interconnecting a 3Com Switch 5500 with any other 3Com device (such as 5500G Switch units) or mix Enhanced Image (EI) Switch 5500 units with Standard Image (SI) units. ■ 3Com strongly recommends that you upgrade all Switches to be interconnected to the latest software agent. ■ 3Com recommends that you remove the configuration file from a Switch unit that has previously been used elsewhere in your network before you interconnect to an existing unit. If you do not do this, problems may be caused by conflicting Switch configurations. Use the dir command from the User View to display the configuration files stored on the Switch and locate the [filename].cfg file. Do NOT under any circumstances remove the 3comoscfg.def file (this is the default configuration file). ■ When a port is operating in XRN Fabric mode it will no longer be configurable in the normal way, that is, you cannot control port features such as auto-negotiation, VLANs, static addresses, STP, Aggregated Links, Resilient Links, and so on. However, it is possible to specify the Fabric VLAN. For a detailed description of how XRN Technology operates and implementation guidelines, please refer to the Configuration Guide on the CD-ROM that accompanies your Switch. DUA1715-0AAA02.book Page 59 Wednesday, March 23, 2005 11:17 AM

Unit Numbering within the Fabric When a Fabric is created using the Switch 5500 the unit numbering can be determined in two ways. ■ You can manually assign unit IDs 1 to 8 to specific units using the change[self-unit, unit-id] to [1-8, auto-numbering] command from the System View. If you manually assign unit IDs to a Switch via the change command the IDs will be retained after a power cycle. If you add a unit to a Fabric that has previously been manually configured with a unit ID and this conflicts with an ID already within the Fabric, then the Switch with the lowest MAC address assumes the ID in question and the other unit will automatically renumber. 3Com recommends that you manually assign the unit IDs within the Fabric if you wish to have predictability of knowing which units have which IDs at all times. ■ Fabric topology is ‘discovered’ and the units auto-number their IDs. Adding and removing units from the Fabric does not cause any renumbering to occur and the Fabric will continue to work normally. Renumbering only occurs when the Fabric is next power cycled if the units are configured to auto-number. The unit LEDs will display the unit number in the Fabric, from 1 to 8. Figure 17 Resilient Fabric example (using 4 units) If you are having problems, refer to “Solving Fabric Formation Problems” on page 66. DUA1715-0AAA02.book Page 60 Wednesday, March 23, 2005 11:17 AM

with the operation of your Switch. There is also an explanation of IP addressing and upgrading software. The topics covered are: ■ Solving Problems Indicated by LEDs ■ Solving Hardware Problems ■ Solving Communication Problems ■ Solving Fabric Formation Problems If you experience a problem that is not listed here, it may be included in the Support section of the SuperStack 4 Switch 5500 Command Reference Guide on the CD-ROM that accompanies your Switch. For Technical Support information, see Appendix D. DUA1715-0AAA02.book Page 61 Wednesday, March 23, 2005 11:17 AM

Solving Problems Indicated by LEDs If the LEDs on the Switch indicate a problem, refer to the list of suggested solutions below. The PWR LED does not light Check that the power cable is firmly connected to the Switch and to the supply outlet. If the connection is secure and there is still no power, you may have a faulty power cord or an internal fault. Firstly, check the power cord by: ■ testing it in another device. ■ connecting a working power cord to the ‘problem’ device then contact your supplier for advice. On powering-up, the PWR LED lights Red The Switch unit has failed its Power On Self Test (POST) because of an internal problem. The fault type will be indicated on the unit LEDs. Contact your supplier for advice. On powering-up, the PWR LED is flashing yellow A port has failed and has been automatically disabled. You can verify this by checking that the Port LED is quickly flashing Yellow. If a port fails, the Switch passes its Power On Self Test and continues to operate normally. A Port LED is flashing yellow The port has failed and has been automatically disabled. The Switch passes its Power On Self Test and continues to operate normally, even if one or more ports are disabled. A link is connected and yet the Port LED does not light Check that: ■ The Switch and the device at the other end of the link (or cable) are connected securely. ■ The devices at both ends of the link are powered-up ■ The quality of cable is satisfactory ■ Auto-negotiation settings are the same at both ends. DUA1715-0AAA02.book Page 62 Wednesday, March 23, 2005 11:17 AM

63 Auto-negotiation problems will occur with 10BASE-T or 100BASE-T where auto-negotiation is disabled and incorrect cables are being used (cross-over or straight) Auto-negotiation problems will occur with fiber if: ■ The Receiver (RX) and Transceiver (TX) cable connectors are swapped ■ Fibers are broken ■ Auto-negotiation differs at either end (a link appears at the ‘fixed’ end and not at the auto-negotiation end) Solving Hardware Problems In the rare event of your Switch unit experiencing a hardware failure, refer to the list of suggested solutions below. A fan failure warning message is received Your Switch has a fan monitoring system that will generate fan failure warning messages. Fan failure could potentially reduce the lifetime of the Switch. The monitoring system polls the fan status at periodic intervals while the unit is powered up. If one fan has failed in the Switch, a warning message will be generated in the following ways: ■ Unit LED — the seven segment display will show a green flashing ‘f’. ■ RMON Trap — if configured, an RMON trap is generated and sent to the management workstation. ■ Command Line Interface — an indication of a general hardware failure is provided through the Top level menu displayed when logging on to the CLI. For more detailed information about the failure select the display logbuffer command. ■ Web interface — an indication of fan failure is provided through the Device Summary table for the specific unit. In addition all Summary tables turn red to indicate the fan failure. If a fan failure warning message is generated: 1 Power off the unit. 2 Check that the air vents are not obstructed. DUA1715-0AAA02.book Page 63 Wednesday, March 23, 2005 11:17 AM

3 Power cycle the unit. To do this, remove and reconnect the AC mains supply. If the unit has no AC main supply, remove and reconnect the DC RPS supply. 4 If another fan failure warning message is generated via the Command Line Interface or the Web interface, return the unit to 3Com. Unit fails, no SNMP fan failure message is received 1 Power cycle the unit. To do this, remove and reconnect the AC mains supply. If the unit has no AC mains supply, remove and reconnect the DC RPS supply. 2 Check the command line interface (display logbuffer command) to determine whether a thermal shutdown has occurred. 3 If no, return the unit: If yes, check that: ■ The air vents are not obstructed. ■ The ambient temperatures and environmental conditions meet those specified in Appendix C. 4 Power cycle the unit. If a further thermal shutdown occurs, and all environmental conditions are satisfactory, return the unit to 3Com. Error message indicating that the SFP transceiver is invalid The Switch has identified that the SFP does not meet the minimum requirements for the Switch and has disabled the port. To correct this problem, completely remove the SFP and replace it with a 3Com approved SFP. See “Approved SFP Transceivers” on page 31. Error message indicating that the SFP transceiver is faulty To correct this problem, completely remove the SFP and then reinsert it. Alternatively, insert another identical SFP. If the problem persists, contact 3Com Technical Support. Solving Communication Problems If you experience communication problems with the Switch, ensure that: ■ The Switch IP address and Management VLAN ID has been configured. DUA1715-0AAA02.book Page 64 Wednesday, March 23, 2005 11:17 AM

65 ■ If the Switch is separated from your management application by a router, ensure that the default gateway IP address within the Switch is the same as the IP address of the router. ■ The Switch’s IP address has been entered correctly in your network management application (such as 3Com Network Director). The following is a brief overview of IP addressing, and how to obtain a registered IP address. IP Addressing To be managed correctly, each device on your network (for example a Switch or Hub) must have a unique IP address. IP addresses have the format n.n.n.n where n is a decimal number between 0 and 255. An example IP address is 192.168.100.8. The IP address is split into two parts: ■ The first part (‘192.168.100’ in the example) identifies the network on which the device resides ■ The second part (‘.8’ in the example) identifies the device within the network The natural subnet mask for this example is 255.255.255.0. If your network has a connection to the external IP network, that is, you access the Internet, you must apply for a registered IP address. How do you obtain a registered IP Address? The IP registration system ensures that every IP address used is unique; if you do not have a registered IP address, you may be using an identical address to someone else and your network will not operate correctly. InterNIC Registration Services is the organization responsible for supplying registered IP addresses. The following contact information is correct at time of publication: World Wide Web site: http://www.internic.net If your IP network is internal to your organization only, that is, you do not access the Internet, you may use any arbitrary IP address as long as it is not being used by another device on your network. 3Com suggests you DUA1715-0AAA02.book Page 65 Wednesday, March 23, 2005 11:17 AM

use addresses in the range 192.168.0.0 to 192.168.255.255 with a subnet mask of 255.255.255.0. These suggested IP addresses are part of a group of IP addresses that have been set aside specially for use ‘in house’ only. Solving Fabric Formation Problems If you are having problems with correctly forming a fabric, first ensure that Spanning Tree is enabled. If it is enabled, do the following: 1 Power off all units in the fabric. 2 Check all the cable connections in the fabric. 3 Check the ports have been enabled as fabric ports. 4 Power on all units in the fabric.

covers the following topics: ■ Upgrading from the Command Line Interface ■ Upgrading from the Bootrom Interface ■ Bootrom Upgrade DUA1715-0AAA02.book Page 67 Wednesday, March 23, 2005 11:17 AM

Upgrading from the Command Line Interface This section describes how to upgrade files to your Switch from the Command Line Interface (CLI). Introduction Before upgrading the software to your Switch from the CLI, it is important to check the contents of the flash to ensure that there is enough space to download the new files. The flash space needed for the new files is approximately 5.5 MB. 1 To check the contents of the flash, logon to your Switch either via a telnet connection or directly via the console to display the User View in the CLI and enter the following: dir unit1>flash: A file list similar to the following is displayed: Directory of unit1>flash:/ 15367 KB total (10215 KB free) 2 You can check the contents of the flash for the remaining units in the fabric by entering: dir unit2>flash: dir unit3>flash: dir unit4>flash: dir unit5>flash: dir unit6>flash: dir unit7>flash: The file list should contain one of each file type (.zip, .def, .cfg and .app). 3 Any additional files should be considered for deletion to allow maximum space for downloading the new files. To delete a file from the list enter: delete/unreserved unit1>flash:/filename 0 -rw- 714784 Apr 02 2005 01:36:16 s4h03_01_00.zip 1 -rw- 11043 Apr 02 2005 01:37:17 3ComOScfg.def 2 -rw- 11427 Apr 02 2005 00:01:01 3ComOScfg.cfg 3 -rw- 4529259 Apr 02 2005 01:39:57 s4b03_01_00s168.app DUA1715-0AAA02.book Page 68 Wednesday, March 23, 2005 11:17 AM

69 To delete files from the list for the remaining units in a fabric, replace unit1 with unit2 (on the next line) and so on for each Switch in the fabric. 4 The /unreserved option will cause the file to be deleted from both the flash and the recycle-bin. To check that deleted files have been removed from the recycle-bin enter the following: reset recycle-bin unit1>flash:/ If the recycle-bin is empty the following is displayed: % File can’t be found “unitN>flash:/” To check that deleted files have been removed from the recycle-bin for the remaining units in a fabric, replace unit1 with unit2 and so on for each Switch in the fabric. The following steps enable you to backup each Switch in the fabric: 1 To back up the default configuration file on each Switch in the fabric, enter: copy unit1>flash:/3ComOScfg.def unit1>flash:/030100cfg.def Replace unit1 with unit2 and so on for each Switch in the fabric. 2 To back up the active configuration file on each Switch in the fabric, enter: copy unit1>flash:/3ComOScfg.cfg unit1>flash:/030100cfg.cfg Replace unit1 with unit2 and so on for each Switch in the fabric. 3 To back up the Web user interface file on each Switch in the fabric, enter: copy unit1>flash:/s4h03_01_00.zip unit1>flash:/030100http.zip Replace unit1 with unit2 and so on for each Switch in the fabric. TFTP To upgrade software to your Switch via TFTP do the following: 1 To download the application file, enter: tftp aaa.aaa.aaa.aaa get s4a03_01_00s168.app DUA1715-0AAA02.book Page 69 Wednesday, March 23, 2005 11:17 AM

(where aaa.aaa.aaa.aaa is the IP address of the TFTP server) s4a indicates the Switch filename, see Table 15 for further details: Table 15 Switch 5500 Filenames 2 To download the Web user interface file, enter: tftp aaa.aaa.aaa.aaa get http.zip 3 To download the default configuration file, enter: tftp aaa.aaa.aaa.aaa get 3ComOScfg.def 4 To download the bootrom file, enter: tftp aaa.aaa.aaa.aaa get s4e002_012_000.btm The bootrom firmware may not require upgrading for every software upgrade, therefore there may not be a new bootrom (.btm) file to download. File Distribution The following commands enable you to distribute your downloaded files to the remaining Switches in the fabric: 1 To copy the new software file to each Switch in the fabric, enter: copy unit1>flash:/s4a03_01_00s168.app unit2>flash:/ Replace unit2 with unit3 and so on for each Switch in the fabric. 2 To copy the new default configuration file to each Switch in the fabric, enter: copy unit1>flash:/3ComOScfg.def unit2>flash:/ Replace unit2 with unit3 and so on for each Switch in the fabric. 3 To copy the new Web user interface file to each Switch in the fabric, enter: copy unit1>flash:/http.zip unit2>flash:/ Replace unit2 with unit3 and so on for each Switch in the fabric. 4 To copy the new Bootrom firmware file to each Switch in the fabric, enter: Filename Prefix Switch s4a SuperStack 4 Switch 5500-SI software s4b SuperStack 4 Switch 5500-EI software s4e SuperStack 4 Switch 5500 bootrom software DUA1715-0AAA02.book Page 70 Wednesday, March 23, 2005 11:17 AM

71 copy unit1>flash:/s4e002_012_000.btm unit2>flash:/ Replace unit2 with unit3 and so on for each Switch in the fabric. Command Line Interface Switch Setup 1 To set the Switch to boot from the new software you have downloaded, enter the following: boot boot-loader unit1>flash:/s4a03_01_00s168.app To set the remaining Switches in the fabric to boot from the new software, replace unit1 with unit2 and so on for each Switch in the fabric. 2 To set the Switch to load the new bootrom firmware, enter: boot bootrom unit1>flash:/s4e002_012_000.btm To set the remaining Switches in the fabric to load the new bootrom firmware, replace unit1 with unit2 and so on for each Switch in the fabric. 3 You will now need to reboot the fabric for the changes to take effect. The Switch will upgrade the bootrom firmware and boot from the specified software .app file. The files that you have saved in the backup phase should be deleted once the upgrade has completed successfully. FTP (via a network port) To upgrade software to your Switch via FTP do the following: 1 Enter the following command from User View: ftp aaa.aaa.aaa.aaa (where aaa.aaa.aaa.aaa is the IP address of the FTP server) If the FTP server has been successfully located, the following information is displayed: Trying...
