NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS. THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY. The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense. The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense. You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: • Turn the television or radio antenna until the interference stops. • Move the equipment to one side or the other of the television or radio. • Move the equipment farther away from the television or radio. • Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.) Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

xxviii Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Opening a TAC Case Using the online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly. To open a case by telephone, use one of the following numbers: Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227) EMEA: +32 2 704 55 55 USA: 1 800 553-2447 For a complete listing of Cisco TAC contacts, go to this URL: http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml TAC Case Priority Definitions To ensure that all cases are reported in a standard format, Cisco has established case priority definitions. Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation. Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation. Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

78-16057-01 Preface Obtaining Additional Publications and Information Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

1-1 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 1 Using Express Setup This chapter provides a quick setup procedure for a standalone switch. Note For setup instructions using the command-line interface (CLI)-based setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.” Note Before connecting the switch to a power source, review the safety warnings in Chapter 3, “Switch Installation.” The setup procedure includes these steps: • Taking Out What You Need, page 1-2 • Powering On the Switch, page 1-3 • Starting Express Setup, page 1-4 • Configuring the Switch Settings, page 1-8 • Where to Go Next, page 1-12

Taking Out What You Need 1-2 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Caution Do not start Express Setup when there are any devices connected to the switch or connect a switch that is already in Express Setup mode to any device other than the PC or workstation that is being used to configure it.

Starting Express Setup 1-4 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 When the switch powers on, it automatically begins the power-on self test (POST), a series of tests that verifies that the switch functions properly. When the switch begins POST, the system LED slowly blinks green. When POST completes, the system LED blinks amber. If POST fails, the system LED remains amber. If POST completes successfully, the system LED rapidly blinks green. If POST fails, see Chapter 4, “Troubleshooting,” to determine a course of action. Starting Express Setup Express Setup is a browser-based program that you can use to set up and configure the switch. You assign the IP information so that the switch can connect to local routers and the Internet. The IP address is also required if you plan to further configure the switch. You do not create a username with Express Setup. Express Setup provides the mimimum configuration to configure a switch. To create a username for the switch, use the Cluster Managment Suite (CMS) or the CLI. Note Before starting Express Setup, verify that the switch has passed POST and that the SYST and STAT LEDs are green. For information about troubleshooting a POST failure, see the “Understanding POST Results” section on page 4-1. You cannot start Express Setup until POST has completed. Caution Do not start Express Setup when there are any devices connected to the switch. The switch acts as a DHCP server during the Express Setup procedure, and only the PC or workstation connected to the switch after Express Startup is started should receive a DHCP address from the switch. all-guides.c om

Front Panel Description 2-4 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Figure 2-2 Catalyst 3560-48PS Switch Front Panel 10/100 Ports You can set the 10/100 ports on the Catalyst 3560 switches to operate in any combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. You can also set these ports for speed and duplex autonegotiation, in compliance with IEEE 802.3AB. (The default setting is autonegotiate.) When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters). Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. 1 10/100 ports 2 SFP module slots 97911 2 1 Catalyst 3560 SERIES PoE-48 SYST RPS STAT DUPLX SPEED PoE MODE 1 2 5 6 7 8 9 10 11 12 13 14 15 16 3 4 1X 2X 15X 16X 17 18 21 22 23 24 25 26 27 28 29 30 31 32 19 20 17X 18X 31X 32X 33 34 37 38 39 40 41 42 43 44 45 46 47 48 35 36 33X 34X 47X 48X 1 2 3 4

78-16057-01 Chapter 2 Product Overview Front Panel Description The10/100 ports on the Catalyst 3560 switches provide PoE support for devices compliant with IEEE 802.3AF and also provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points. Each of the Catalyst 3560-24PS switch 10/100 ports can deliver up to 15.4 W of PoE. On the Catalyst 3560-48PS switch, any 24 of the 48 10/100 ports can deliver 15.4 W of PoE, or any combination of the 10/100 ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum switch power output of 370 W. On a per-port basis, you can control whether or not a Catalyst 3560 10/100 port automatically provides power when an IP phone or an access point is connected. CMS and the CLI provide two PoE settings for each 10/100 port: Auto and Never. When you select the Auto setting, the port only provides power if a valid powered device, such as an IEEE 802.3AF-compliant powered device, a Cisco pre-standard IP phone, or a Cisco pre-standard Cisco access point, is connected to it. The Auto setting is the default. However, when you select the Never setting, the port does not provide power even if a Cisco IP phone or an access point is connected to it. Note You also can connect a Cisco IP Phone or Cisco Aironet Access Point to a Catalyst 3560 switch 10/100 port and to an AC power source for redundant power. The powered device might switch to the AC power source as its primary power source upon being connected to it. In that case, the 10/100 PoE port becomes the backup power source for the powered device. If the primary source fails, the second power source becomes the primary power source to the powered device. During the power transfer, an IP Phone might reboot or reestablish link with the switch. For information about Cisco IP Phones and Cisco Aironet Access Points, refer to the documentation that came with your IP phone or access point.

Front Panel Description 2-6 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Note 100BASE-TX and 1000BASE-T traffic requires Category 5 cable. 10BASE-T traffic can use Category 3 or Category 4 cables. When connecting the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the cable is a straight-through cable. When connecting the switch to switches or hubs, use a crossover cable. When using a straight-through or crossover cable for 1000BASE-T connections, be sure to use a twisted four-pair, Category 5 cable for proper operation. Pinouts for the cables are described in Appendix B, “Connector and Cable Specifications.” Note You can use the mdix auto interface configuration command in the CLI to enable the automatic medium-dependent interface crossover (Auto-MDIX) feature. When the feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100 or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection. The Auto-MDIX feature is disabled by default. For configuration information for this feature, refer to the switch software configuration guide or the switch command reference. Note Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3AF, might not support PoE when connected to the switches by a crossover cable.

78-16057-01 Chapter 2 Product Overview Front Panel Description SFP Module Slots The SFP module slots support the SFP modules listed in the Catalyst 3560 release notes. SFP Modules The Catalyst 3560 switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections. These transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP module slot. You can use the SFP modules for Gigabit uplink connections to other switches. You use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP module. You use Category 5 cable with RJ-45 connectors to connect to a copper SFP module. The Catalyst 3560 models support these Cisco SFP modules: • 1000BASE-LX • 1000BASE-SX • 1000BASE-ZX • 1000BASE-T • CWDM For more information about these SFP modules, refer to your SFP module documentation. LEDs You can use the switch LEDs to monitor switch activity and its performance. Figure 2-3 shows the switch LEDs and the Mode button that you use to select one of the port modes. All of the LEDs described in this section are visible in the Cluster Management Suite (CMS). The switch online help describes how to use CMS to configure and monitor individual switches and switch clusters. all-guides.c om

CMS is already installed on the switch, and no additional installation is required. From CMS, you can fully configure and monitor a switch or switch clusters, display network topologies to gather link information, and display switch images to modify switch- and port-level settings. For more information, refer to the switch software configuration guide on Cisco.com, the CMS, or the online help. • Cisco IOS command-line interface (CLI) The switch CLI is based on Cisco IOS software and is enhanced to support desktop-switching features. You can fully configure and monitor the switch and switch cluster members from the CLI. You can access the CLI either by connecting your management station directly to the switch console port or by using Telnet from a remote management station. Refer to the Catalyst 3560 Switch Command Reference on Cisco.com for more information.

78-16057-01 Chapter 2 Product Overview Management Options For setup instructions that use the CLI, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.” • CiscoView application The CiscoView device-management application displays the switch image that you can use to set configuration parameters and to view switch status and performance information. The CiscoView application, which you purchase separately, can be a standalone application or part of a Simple Network Management Protocol (SNMP) platform. Refer to the CiscoView documentation for more information. • SNMP network management You can manage switches from a SNMP-compatible management station that is running platforms such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of Management Information Base (MIB) extensions and four Remote Monitoring (RMON) groups. Refer to the switch software configuration guide on Cisco.com and the documentation that came with your SNMP application for more information. Network Configurations Refer to the switch software configuration guide on Cisco.com for an explanation of network configuration concepts.

Preparing for Installation 3-8 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Installation Guidelines When determining where to place the switch, be sure to observe these requirements: • For copper Ethernet ports, including 10/100 ports and 1000BASE-T SFP module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters). • Table 3-1 lists the cable specifications for 1000BASE-SX, 1000BASE-LX, and 1000BASE-ZX fiber-optic SFP module connections. Each port must match the wave-length specifications on the other end of the cable, and for reliable communications, the cable must not exceed the stipulated cable length. Table 3-1 Fiber-Optic SFP Module Port Cabling Specifications SFP Module Wavelength (nanometers) Fiber Type Core Size (micron) Modal Bandwidth (MHz/km) Cable Distance 1000BASE-SX 850 MMF 62.5 62.5 50 50 160 200 400 500 722 feet (220 m) 902 feet (275 m) 1640 feet (500 m) 1804 feet (550 m) 1000BASE-LX/LH 1300 MMF1 SMF 62.5 50 50 9/10 500 400 500 — 1804 feet (550 m) 1804 feet (550 m) 1804 feet (550 m) 32,810 feet (10 km) 1000BASE-ZX 1550 SMF 9/10 — 43.4 to 62 miles (70 to 100 km)2

78-16057-01 Chapter 3 Switch Installation Preparing for Installation Note When using shorter distances of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver. When the fiber-optic cable span is less than15.43 miles (25 km), you should insert a 5-decibel (dB) or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module at each end of the link. • Operating environment is within the ranges listed in Appendix A, “Technical Specifications.” • Clearance to front and rear panels is such that – Front-panel indicators can be easily read. – Access to ports is sufficient for unrestricted cabling. – Rear-panel power connector is within reach of an AC power receptacle. • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure the cabling is safely away from other devices that might damage the cables. CWDM 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 SMF 9/125 — 62 miles (100 km) 1. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m). 2. 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on the fiber quality, the number of splices, and the connectors.

Refer to the Catalyst 3560 release notes for the list of SFP modules that the Catalyst 3560 switches support. Each port must match the wave-length specifications on the other end of the cable, and

78-16057-01 Chapter 3 Switch Installation Installing and Removing SFP Modules for reliable communications, the cable must not exceed the stipulated cable length. See the “Installation Guidelines” section on page 3-8 for cable stipulations for SFP connections. Use only Cisco SFP modules on the Catalyst 3560 switch. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the switch. For detailed instructions on installing, removing, and cabling the SFP module, refer to your SFP module documentation. Installing SFP Modules into SFP Module Slots Figure 3-14 shows an SFP module that has a bale-clasp latch. Caution We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module. Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary. Figure 3-14 SFP Module with a Bale-Clasp Latch 86575

Step 6 Insert the cable connector into the SFP module: • For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the SFP module. • For copper SFP modules, insert the RJ-45 cable connector into the SFP module. Note When connecting to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 cable. Removing SFP Modules from SFP Module Slots To remove an SFP module from a module receptacle, follow these steps: Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis. Step 2 Disconnect the cable from the SFP module, and insert a dust plug into the cable end. Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX). Step 3 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean. Step 4 Unlock and remove the SFP module, as shown in Figure 3-16.

78-16057-01 Chapter 3 Switch Installation Connecting to the 10/100 Ports Connecting to the 10/100 Ports The switch 10/100 ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage. Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. To maximize performance, choose one of these methods for configuring the Ethernet ports: • Let the ports autonegotiate both speed and duplex. • Set the port speed and duplex parameters on both ends of the connection. You can configure the 10/100 ports on the Catalyst 3560 switch either to automatically provide PoE when a Cisco IP Phone, Cisco Aironet Access Point, or end device compliant with IEEE 802.3AF is connected or to never to provide PoE, even if an IP phone or an access point is connected. The default setting is Auto. To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

Connecting to the 10/100 Ports 3-30 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Follow these steps to connect to 10BASE-T or 100BASE-TX devices: Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through cable to an RJ-45 connector on the front panel. (See Figure 3-17.) When connecting to switches or repeaters, use a crossover cable. (See the “Cable and Adapter Specifications” section on page B-5 for cable-pinout descriptions.) Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only standard-compliant cabling can be used to connect Cisco pre-standard IP Phones or wireless access points or IEEE 802.3AF-compliant devices to PoE ports. A cable or device that causes a PoE fault must be removed from the network. Note You can use the mdix auto interface configuration command in the CLI to enable the automatic medium-dependent interface crossover (Auto-MDIX) feature. When the Auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100 or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection. The Auto-MDIX feature is disabled by default. For configuration information for this feature, refer to the switch software configuration guide or the switch command reference. Note The Catalyst 3560 switch can connect to a Cisco IP Phone through a straight-through, twisted four-pair Category 5 cable. The rear panel of the Cisco IP Phone might have more than one RJ-45 connector. Use the LAN-to-phone connector to connect the IP phone to the switch. Refer to the Cisco IP Phone documentation for more information about connecting devices to it.

78-16057-01 Chapter 3 Switch Installation Connecting to the 10/100 Ports Note Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3AF, might not support PoE when connected to the switches by a crossover cable. Step 2 Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both the switch and the connected device have established link. The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This takes about 30 seconds, and then the port LED turns green. If the port LED does not turn on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See Chapter 4, “Troubleshooting,” for solutions to cabling problems. Step 3 Reconfigure and reboot the connected device, if necessary. Step 4 Repeat Steps 1 through 3 to connect each device.

Connecting to SFP Modules 3-32 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Connecting to SFP Modules This section describes how to connect to SFP modules. For instructions on how to connect to fiber-optic SFP modules, see the “Connecting to Fiber-Optic SFP Modules” section. For instructions on how to connect to copper 1000BASE-T SFP modules, see the “Connecting to 1000BASE-T SFP Modules” section. For instructions about how to install or remove an SFP module, see the “Installing and Removing SFP Modules” section on page 3-24. Connecting to Fiber-Optic SFP Modules Follow these steps to connect a fiber-optic cable to an SFP module: Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light. Before connecting to the SFP module, be sure that you understand the port and cabling stipulations in the “Installation Guidelines” section on page 3-8 and in the “SFP Module Slots” section on page 2-7. See Appendix B, “Connector and Cable Specifications,” for information about the LC on the SFP module. Step 1 Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use. Step 2 Insert one end of the fiber-optic cable into the SFP module port (see Figure 3-18). Step 3 Insert the other cable end into a fiber-optic connector on a target device. Step 4 Observe the port status LED. The LED turns green when the switch and the target device have an established link. The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device. See Chapter 4, “Troubleshooting,” for solutions to cabling problems.

4-1 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 4 Troubleshooting The LEDs on the front panel provide troubleshooting information about the switch. They show failures in the power-on self-test (POST), port-connectivity problems, and overall switch performance. For a full description of the switch LEDs, see the “LEDs” section on page 2-7. You can also get statistics from the browser interface, from the command-line interface (CLI), or from a Simple Network Management Protocol (SNMP) workstation. Refer to the software configuration guide, the switch command reference guide on Cisco.com, or the documentation that came with your SNMP application for details. This chapter describes these topics for troubleshooting problems: • Understanding POST Results, page 4-1 • Diagnosing Problems, page 4-3 Understanding POST Results When the switch powers on, it automatically begins the power-on self test (POST), a series of tests that verifies that the switch functions properly. When the switch begins POST, the system LED slowly blinks green. When POST completes, the system LED blinks amber. If POST fails, the system LED remains amber. If POST completes successfully, the system LED rapidly blinks green. Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.

Clearing the Switch IP Address and Configuration 4-2 Catalyst 3560 Switch Hardware Installation Guide 78-16057-01 Clearing the Switch IP Address and Configuration If you have configured a new switch with a wrong IP address, or if all the switch LEDs start blinking when you are trying to enter Express Setup mode, you can clear the IP address that is configured on the switch. Note This procedure clears the IP address and all configuration information stored on the switch. Do not follow this procedure unless you want to completely reconfigure the switch. To clear the IP address and the switch configuration information, follow these steps: Step 1 Press and hold the Mode button, as shown in Figure 1-4 on page 1-5. The switch LEDs begin blinking after about 2 seconds. Note If the switch is not configured, the LEDs are all green. You can omit Step 2 and run Express Setup to configure the switch. Step 2 Continue holding down the Mode button. The LEDs stop blinking after 8 additional seconds, and then the switch reboots. Note These steps only work on a previously-configured switch. The switch now behaves like an unconfigured switch. You can configure the switch by using Express Setup as described in these sections. • “Starting Express Setup” section on page 1-4 • “Configuring the Switch Settings” section on page 1-9 • “Verifying Switch IP Address (Optional)” section on page 1-10

78-16057-01 Chapter 4 Troubleshooting Diagnosing Problems You can also configure the switch by using the command-line interface (CLI) setup procedure described in these sections: • “Starting the Terminal-Emulation Software” section on page C-5 • “Entering the Initial Configuration Information” section on page C-7 Diagnosing Problems Common switch problems fall into these categories: • Poor performance • No connectivity • Corrupted software Table 4-1 describes how to detect and resolve these problems.
