A standard rack-mount kit is included for mounting the switch in a standard 19-inch (48.3 cm) equipment rack with two unobstructed outer posts. This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the switch.

Required Installation Tools

You will need the following tools and equipment to install the switch chassis in a rack:

Rack-Mounting the Catalyst 2948G and 2980G Switches

To install Catalyst 2940G and 2980G switches in a 19-inch rack, follow these steps:

Note   Some equipment racks have a power strip along the length of one of the rear posts. If the rack has this feature, consider the position of the strip when planning fastener points. Before installing the L brackets on the chassis, determine whether to install the chassis from the front or the rear of the rack.

Step 2   Attach the left and right L brackets using the four M4 Phillips pan-head screws provided in the rack-mount kit (see Figure 3-1).

The L brackets connect the switch chassis to the rack. You can mount the L brackets to the front- or rear-mounting holes of the chassis, depending on which end is in the front of the rack.

---

Note    The Catalyst 2948G switch is shown in the rack-mounting illustrations. The rack-mounting procedure for the Catalyst 2980G switch is the same.

To install a Catalyst 2948G-GE-TX switch, follow the steps described in these procedures:

Rack-Mounting the Catalyst 2948G-GE-TX Switch

To install a Catalyst 2948G-GE-TX switch in a 19-inch rack (24-inch racks require optional mounting hardware), follow the instructions described in these procedures:

Removing Screws from the Switch

If you plan to install the switch in a rack, you must first remove screws in the switch chassis so that mounting brackets can be attached. Figure 3-3 shows how to remove the chassis screws from the switch.

Attaching Brackets to the Switch

The bracket orientation and the brackets you use depend on whether you are attaching the brackets for a 19-inch or a 24-inch rack. For 19-inch racks, use the brackets that are included in the mounting kit.

Note   Installing the switch in a 24-inch rack requires an optional bracket kit not included with the switch. You can order a kit containing the 24-inch rack-mounting brackets and hardware (order part number RCKMNT-1RU=) from Cisco.

Figure 3-4 through Figure 3-9 show how to attach each type of bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

Mounting the Switch in a Rack

After the brackets are attached to the switch, use the four supplied number-12 Phillips machine screws to securely attach the brackets to the rack, as shown in Figure 3-10.

Attaching the Cable Guide

We recommend attaching the cable guide to the left or right bracket to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack. Use the supplied black screw, as shown in Figure 3-11, to attach the cable guide to the left or right bracket.

Note   The Catalyst 2948G-GE-TX switch ships with a special cable guide, as shown in Figure 3-11. This cable guide secures up to 48 cables. Use the supplied black screw to mount it on the left or right bracket.

Wall-Mounting the Catalyst 2948G-GE-TX Switch

To install the Catalyst 2948G-GE-TX switch on a wall, follow the instructions in these procedures:

Attaching the Brackets to the Switch for Wall-Mounting

Figure 3-12 shows how to attach a 19-inch bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

Attaching the RPS Connector Cover

If you are not using a Cisco RPS with your switch, use the two Phillips pan-head screws to attach the RPS connector cover to the back of the switch before you mount it, as shown in Figure 3-13.

Warning If an RPS is not connected to the switch, install an RPS connector cover on the back of the switch. Statement 265

Mounting the Switch on a Wall

For the best support of the switch and cables, make sure the switch is attached securely to wall studs or to a firmly attached plywood mounting backboard. Mount the switch with the front panel facing up, as shown in Figure 3-14.

Warning To comply with safety regulations, mount the switches on a wall with the front panel facing up. Statement 266

Mounting the Catalyst 2948G-GE-TX Switch on a Table or Shelf

To install the switch on a table or shelf, follow these steps:

Step 2   Attach the four rubber feet to the recessed areas on the bottom of the unit.

Step 3   Place the switch on the table or shelf near an AC power source.

Connecting Power to the Switches

To connect power to Catalyst 2948G, 2948G-GE-TX, and 2980G switches, follow these steps:

Step 2   Plug the power cord into the chassis.

Step 3   Connect the other end of the power cord to an AC-power input source.

Step 4   Verify power supply operation by checking the front panel power supply LEDs:

From the system console, enter the show system command to display the power supply and system status. For more information on commands, refer to the command reference for your switch.

If the LEDs or the show system command indicate a power problem or other system problem, see "Translated Safety Warnings" for more information.

Connecting to 10/100 and 10/100/1000 Ports

The 10/100 ports on the Catalyst 2948G and 2980G switches configure themselves to operate at the speed and duplex settings of attached devices. They operate at 10 or 100 Mbps in half- or full-duplex mode. If the attached devices do not support autonegotiation, the speed should resolve correctly. You can also explicitly set the speed and duplex parameters.

The 10/100/1000 ports on the Catalyst 2948G-GE-TX switches configure themselves to operate at the speed setting of attached devices. These ports operate at 10, 100, or 1000 Mbps in full-duplex mode. If the attached devices do not support autonegotiation, you can set the speed.

Connecting devices that do not autonegotiate or devices with manually set speed and duplex parameters can reduce performance or result in link failures between the devices. To maximize performance, choose one of these methods for configuring the ports:

Caution   To comply with the intrabuilding lightning surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

Caution   To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

To connect the switch to 10BASE-T, 100BASE-TX, or 1000BASE-T devices, follow these steps:

Note   When connecting to 1000BASE-T devices, be sure to use a four twisted-pair, Category 5 cable.

Step 2   Insert the other cable end in an RJ-45 connector on the target device.

Step 3   Observe the port STATUS LED:

The LED does not light when the target device is not turned on, a cable problem exists, or a problem exists with the adapter installed in the target device.

If the STATUS LED does not turn green or does not light at all, see "Troubleshooting the Installation" section for solutions to cabling problems.

Step 4   Reconfigure and restart the target device if necessary.

Step 5   Repeat Steps 1 through 4 to connect each port.

Connecting a Terminal to the Console Serial and Ethernet Management Ports

The console serial and Ethernet management ports are located on the front panel of the Catalyst 2948G, 2948G-GE-TX, and 2980G switches. These ports use an RJ-45 media-dependent interface crossed-over (MDIX) connector, as shown in Figure 3-16. For information about port pinouts, see "Specifications."

The Catalyst 2948G switches have a 10BASE-T management port. The Catalyst 2948G-GE-TX and 2980G-A switches have a 10/100BASE-T management port.

Note   The MDIX Ethernet ports are crossed over internally. For an MDI-to-MDI or MDIX-to-MDIX connection, use a crossover cable. For an MDI-to-MDIX connection, use a straight-through cable, which allows the Tx pins to connect with the Rx pins.

Verifying Switch Operation

After you have connected all the interfaces, check all connections, and then perform the following steps to power on the system to verify that it is operational:

Step 2   Check the console terminal and make sure it is powered on.

Step 3   Connect the power cords to the switch.

Step 4   Verify that the PSI or PWR LEDs on the power supply front panel is green.

Step 5   Listen for the system fans to ensure that they are operational.

Step 6   While the system initializes, check that the STATUS LED on the supervisor engine is amber until the boot is complete.

---

Note    Many of the interface LEDs do not illuminate until you configure the interfaces.

---

When the system boot is complete (it takes a few seconds), the supervisor engine begins to initialize the interfaces. During this initialization, the interface LEDs flash on and off. When initialization is complete, the console screen displays a script and system banner.

Note   When interface LEDs are on, the interface ports may not be functional or enabled. Although the LEDs for many interface types might turn on at system startup, they do not indicate an accurate status until the interface is configured.

Note   If the system does not complete this verification process, see "Troubleshooting the Installation."
