the switch in your rack. Optional procedures such as connecting the stacking ports or installing a plug-in module are also described. Unpacking a S3100 Series Switch To unpack your switch, follow these steps. NOTE: Before unpacking the switch, inspect the container and immediately report any evidence of damage. When unpacking each S3100 series switch, make sure that the following items are included: • One S3100 series switch. • One RJ-45 to DB-9 female cable. • One Dell ReadyRails™ kit for rack installation, two mounting brackets, bolts, and cage nuts. • One set of self-adhesive rubber pads for free-standing installation (four pads are included). • One PSU. • Getting Started Guide. • Safety and Regulatory Information. • Warranty and Support Information. • Software License Agreement. 1. Place the container on a clean, flat surface and cut all straps securing the container. 2. Open the container or remove the container top. 3. Carefully remove the switch from the container and place it on a secure and clean surface. 4. Remove all packing material. 5. Inspect the product and accessories for damage. Installing a Power Supply To install a power supply, follow these steps. CAUTION: Remove the power cable from the power supplies prior to removing the power supply module itself. Power must not be connected prior to insertion in the chassis. CAUTION: To prevent electrical shock, ensure that the system is grounded properly. If you do not ground your equipment correctly, excessive emissions may result. To ensure that the power cables meet your local electrical requirements, use a qualified electrician. WARNING: ESD damage can occur if components are mishandled. Always wear an ESD- preventive wrist or heel ground strap when handling the system and its components. 26 Installation

the PSU or the chassis. Ensure that you install the PSU correctly. When you install the PSU correctly, the power connector is on the right side of the PSU. NOTE: The PSUs are field replaceable. When running with full redundancy (two power supplies installed and running), you can remove and replace one PSU while the other PSU is running, without disrupting traffic. 1. Remove the PSU slot cover from the PSU side of switch. You can select either of the two PSU slots, however, if you are using a single PSU, Dell Networking recommends using power supply 1 (PSU1) as the blank plate slot. 2. Remove the PSU from the electrostatic bag. 3. Insert the PSU into the switch PSU slot (insert the PSU-exposed PCB edge connector first). The PSU slot is keyed such that the PSU can only be fully inserted in one orientation. 4. Plug in the AC cord from the switch PSU to the external power source, such as an AC wall outlet. NOTE: The system powers up as soon as the cables are connected between the power supply and the power source. If you have not yet installed the switch in a rack, defer this step until you are ready to power up the system. 5. If you have a redundant PSU (a second PSU), repeat steps 1 through 5 using the second PSU slot on the S3100 series system. 6. If you use a single PSU, install a blank plate in the other PSU slot. Figure 19. Installing a Power Supply Installing a Fan Tray To install a fan tray, follow these steps: NOTE: The fan tray is hot-swappable. 1. Take the fan tray out of the shipping box. 2. Use the grab handle on the fan tray to slide it into the bay. 3. Tighten the captive screws on the fan tray with a screwdriver. Ensure that the fan tray is secure. Installation 27

Installing a Plug-In Module (Optional) The S3100 series switches support SFP+ and 10GBase-T plug-in modules in the expansion slots on the PSU side of the switch. CAUTION: The plug-in modules are not hot-swappable. To install a plug-in module, follow these steps: 1. Insert the module into an expansion slot. 2. Reboot the switch. The switch recognizes the new module. After a module is recognized, its configuration is stored locally on the switch as the switch default. The module configuration appears in the running configuration for informational purposes. For more information, see the Dell Configuration Guide for the S3100 Series. Install Rack or Cabinet Hardware You may either place the switch on the rack shelf or mount the switch directly into a 19" wide, EIA-310- E-compliant rack (four-post, two-post, or threaded methods). The ReadyRails system is provided for one 1U front-rack and two-post installations. The system includes two separately packaged rail assemblies. WARNING: This is a condensed reference. Read the safety instructions in your Safety, Environmental, and Regulatory information booklet before you begin. NOTE: The illustrations in this document are not intended to represent a specific switch. NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace. 28 Installation

• Rack loading — Overloading or uneven loading of racks may result in shelf or rack failure, this can cause damage to the equipment and possible personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting at the bottom of the rack, then work to the top. Do not exceed your rack load rating. • Power considerations — Connect only to the power source specified on the unit. When you install multiple electrical components in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded power sources and extension cords present fire and shock hazards. • Elevated ambient temperature — If you install the system in a closed rack assembly, the operating temperature of the rack environment may be greater than the room ambient temperature. Use care not to exceed the 40°C maximum ambient temperature of the switch. • Reduced air flow — Install the equipment in the rack so that the amount of airflow required for safe operation of the equipment is not compromised. • Reliable earthing — Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections other than the direct connections to the branch circuit; for example, use of power strips. • Do not mount the equipment with the PSU side facing in the downward position. Installing the Dell ReadyRails System The ReadyRails rack mounting system is provided to easily configure your rack for system installation. You can install the ReadyRails system using the 1U tool-less method or one of three possible 1U tooled methods (two-post flush mount, two-post center mount, or four-post threaded). 1. With the ReadyRails flange ears facing outward, place one rail between the left and right vertical posts. Align and seat the rear flange rail pegs in the rear vertical post flange. Item 1 of the following illustration and its extractions show how the pegs appear in both the square and non-threaded round holes. 2. Align and seat the front flange pegs in the holes on the front side of the vertical post. See item 2 in the following illustration. 3. Repeat this procedure for the second rail. 4. To remove each rail, pull on the latch release button on each flange ear and unseat each rail. See item 3 in the following illustration. Installation 29

Configuring a Two-Post Flush-Mount To install your switch using a two-post flush-mount configuration, follow these steps. 1. For this configuration, remove the castings from the front side of each ReadyRails assembly. See item 1 in the following illustration. To remove the two screws from each front flange ear (on the switch side of the rail) and remove each casting, use a Torx driver. Retain the castings for future rack requirements. It is not necessary to remove the rear flange castings. 2. Attach one rail to the front post flange with two user-supplied screws. See item 2 in the following illustration. 3. Slide the plunger bracket forward against the vertical post and secure the plunger bracket to the post flange with two user-supplied screws. See item 3 in the following illustration. 4. Repeat this procedure for the second rail. 30 Installation

Configuring a Two-Post Center-Mount To install your switch in a two-post center-mount configuration, follow these steps. 1. Slide the plunger bracket rearward until it clicks into place and secure the bracket to the front post flange with two user-supplied screws. See item 1 in the following illustration. 2. Slide the back bracket towards the post and secure it to the post flange with two user-supplied screws. See item 2 in the following illustration. 3. Repeat this procedure for the second rail. Installation 31

Configuring a Four-Post Thread To install your switch in a four-post thread configuration, follow these steps. 1. For this configuration, remove the flange ear castings from each end of the ReadyRails assemblies. To remove the two screws from each flange ear and remove each casting, use a Torx driver. See item 1 in the following illustration. Retain the castings for future rack requirements. 2. For each rail, attach the front and rear flanges to the post flanges with two user-supplied screws at each end. See item 2 in the following illustration. 32 Installation

Installing a 1U Two-Post You can install the switch in 1U two-post (flush and center) configurations. Slide the system into the rails in the same manner as the four-post configurations. Installing a 1U Front-Rack To install the switch in a 1U front-rack configuration, configure the rails that are attached to the system. 1. Attach the switch rails (inner chassis members) to the switch. Item 3 in the following illustration shows the detail for the front standoff with the locking tab. Installation 33

2. After you have installed both switch rails, line them up on the previously mounted ReadyRails and slide the switch in until it is flush with the front of the rack. About three inches before you fully insert your switch, the rail locking feature engages to keep the switch from inadvertently sliding out of the rack and falling. NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace. 34 Installation

Connecting the Stacking Ports (Optional) For the S3124P or S3148P platforms, you can connect up to six switches to operate as a single unit, using two fixed mini-SAS stacking connectors on the PSU side. When you connect multiple switches together through the stack ports, they operate as a single unit with up to 288 front panel ports. The stack operates and is managed as a single entity. NOTE: The S3124P and S3148P platforms support stacking with Dell Networking OS 9.8(2.0). Stacks must be either all S3124P or S3148P platforms, you cannot combine different platforms into one stack. The S3124 and S3124F platforms do not support stacking with Dell Networking OS 9.8(2.0). Dell recommends installing the switches connected in a ring topology. Assemble and cable the stack of switches before powering up and configuring it. To install your switches in a ring topology, follow these steps. 1. Connect one of the mini-SAS cables into either of the stacking ports of the top switch and the switch directly below it. As necessary, use a separately purchased, longer (1 meter or 3 meter) mini-SAS cable to connect the switches. 2. Repeat this process until all the devices are connected. 3. Use the remaining stacking cable to connect the two remaining stacking ports together so that a ring topology is assembled. Installation 35

A stack of three switches connected in a ring topology has these physical connections between the switches: 1. The bottom mini-SAS port on Unit 1 is connected to the top mini-SAS port on Unit 2. 2. The bottom mini-SAS port on Unit 2 is connected to the top mini-SAS port on Unit 3. 3. The bottom mini-SAS port on Unit 3 is connected to the top mini-SAS port on Unit 1. After you power up a stack for the first time, the switches elect a master switch, which may occupy any location in the stack. The Master LED on the front panel is illuminated on the master unit. If a master failure is detected in the stack, the stacking feature supports a standby unit that assumes the master unit role. The standby unit is automatically selected in the stack. When a master failure is detected, the standby unit initializes the control plane and enables all other stack units with the current configuration. The standby unit maintains a synchronized copy of the running configuration for the stack. NOTE: You can (optionally) use the CLI to assign the master unit role, or select a different stack member as the standby unit, based on priority or MAC address. For more information, see the Dell Configuration Guide for the S3100 Series or the Dell Command Line Reference Guide for the S3100 Series. 36 Installation

Navigating CLI Modes The Dell Networking OS prompt changes to indicate the CLI mode. Move linearly through the command modes, except for the end command that takes you directly to EXEC Privilege mode, and the exit command that moves you up one command mode level. Accessing the Console The console port is on the I/O side of the chassis (item 1 in the following illustration). Figure 28. Console Port Location NOTE: You must have a password configured on a virtual terminal line before you can Telnet into the system. Therefore, use a console connection when connecting to the system for the first time. Before starting this procedure, be sure that you have a terminal emulation program already installed on your PC. 40 Installing the Software

available from any serial port using the local CLI. Only one serial console session at a time is supported. 1. Install an RJ-45 copper cable into the console port. To connect the console port to a terminal server, use a rollover cable. 2. Connect the other end of the cable to the DTE terminal server. 3. Set the default terminal settings as follows. • 9600 baud rate. • No parity. • Eight data bits. • One stop bit. • No flow control. Access the Console Port with a DB-9 Adapter If the DTE has a DB-9 interface, you can connect to the console using an RJ-45 to DB-9 adapter along with the RJ-45 rollover cable. The following table lists the pin assignments.

You must configure the system using the CLI. Installing the Software 41

To enable Layer 2 data transmissions through an individual interface, use the switchport command in INTERFACE mode. You cannot configure switching or Layer 2 protocols such as spanning tree protocol (STP) on an interface unless the interface has been set to Layer 2 mode. 1. Enable the interface. INTERFACE mode no shutdown 2. Place the interface in Layer 2 (switching) mode. INTERFACE mode switchport To view the interfaces in Layer 2 mode, use the show interfaces switchport command in EXEC mode. Configuring a Host Name The host name appears in the prompt. The default host name is Dell. Host names must start with a letter, end with a letter or digit, and must have characters, letters, digits, and hyphens in the string. • Create a new host name. CONFIGURATION mode hostname name Accessing the System Remotely You can configure the system to be accessed remotely by Telnet. The system has a dedicated management port and a management routing table that is separate from the IP routing table. 1. Configure an IP address for the management port (Configuring the Management Port IP Address). 2. Configure a management route with a default gateway (Configuring the Management Route). 3. Configure a username and password (Configuring the Username and Password). Configuring the Management Port IP Address In order to access the system remotely, assign IP addresses to the management ports. 1. Enter INTERFACE mode for the management port. CONFIGURATION mode 42 Installing the Software

2. Assign an IP address to the interface. INTERFACE mode ip address ip-address/mask 3. Enable the interface. INTERFACE mode no shutdown Configuring the Management Route Define a path from the S3100 series system to the network from which you will remotely access the system. Management routes are separate from IP routes and are used to manage the system through the management port. • Configure a management route to the network from which you will access the system. CONFIGURATION mode management route ip-address/mask gateway Configuring the Username and Password To access the system remotely, configure a system username and password. • Configure a username and password to access the system remotely. CONFIGURATION mode username username password [encryption-type] Configuring the Enable Password Access EXEC Privilege mode using the enable command. EXEC Privilege mode is unrestricted by default. As a basic security measure, configure a password. There are two types of enable passwords: • enable password — stores the password in the running/startup configuration using a data encryption standard (DES)-encryption method. • enable secret — stores the password in the running/startup configuration using a stronger, MD5- encryption method. Dell Networking recommends using the enable secret password. • Create a password to access EXEC Privilege mode. CONFIGURATION mode enable [password | secret] [level level] [encryption-type] password Installing the Software 43

The default VLAN (VLAN 1) is part of the system startup configuration and does not require configuration. To configure a port-based VLAN, create the VLAN and then add physical interfaces or port channel (LAG) interfaces to the VLAN. • Configure a port-based VLAN (if the vlan-id is different from the Default VLAN ID) and enter INTERFACE VLAN mode. CONFIGURATION mode interface vlan vlan-id After you create a VLAN, assign interfaces in Layer 2 mode to the VLAN to activate the VLAN. To view the configured VLANs, use the show vlan command in EXEC Privilege mode. Assigning Interfaces to a VLAN You can only assign interfaces in Layer 2 mode to a VLAN using the tagged and untagged commands. To place an interface in Layer 2 mode, use the switchport command. You can designate Layer 2 interfaces as tagged or untagged. When you place an interface in Layer 2 mode using the switchport command, the interface automatically designates untagged and is in the Default VLAN. To tag frames leaving an interface in Layer 2 mode, assign that interface as tagged to a port-based VLAN to tag it with that VLAN ID. To move untagged interfaces from the Default VLAN to another VLAN, use the untagged command. 1. Tag interfaces. Access INTERFACE VLAN mode of the VLAN to which you want to assign the interface. CONFIGURATION mode interface vlan vlan-id 2. Enable an interface to include the IEEE 802.1Q tag header. INTERFACE mode tagged interface This command is available only in VLAN interfaces. 3. Move untagged interfaces. Access INTERFACE VLAN mode of the VLAN to which you want to assign the interface. CONFIGURATION mode interface vlan vlan-id 4. Configure an interface as untagged. INTERFACE mode 44 Installing the Software

To view which interfaces are tagged or untagged and to view which VLAN the interfaces belong, use the show vlan command. To view just the interfaces that are in Layer 2 mode, use the show interfaces switchport command in EXEC Privilege mode or EXEC mode. Assigning an IP Address to a VLAN VLANs are a Layer 2 feature. For two physical interfaces on different VLANs to communicate, assign an IP address to the VLANs to route traffic between the two interfaces. The shutdown command in INTERFACE mode does not affect Layer 2 traffic on the interface. NOTE: You cannot assign an IP address to the Default VLAN, which, by default, is VLAN 1. To assign another VLAN ID to the Default VLAN, use the default vlan-id vlan-id command from the configuration mode. • Access INTERFACE VLAN mode of the VLAN to which you want to assign the IP address. INTERFACE mode ip address ip-address mask [secondary] Configure an IP address and mask on the interface. Connect the System to the Network After you have completed the hardware installation and software configuration for the system, connect to your company network by following your company’s cabling requirements.
