Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. |
This chapter describes how to install the Catalyst 2948G and 2980G switches. For first-time installations, perform the procedures in the following sections in the order listed:
 |
Note Before starting the installation procedures in this chapter, complete the site planning checklist in "Site Planning." |
|
Note Do not discard the shipping container after you unpack the switch. Flatten the shipping cartons and store them. You will need the container if you need to move or ship the switch in the future. Repacking instructions are provided in "Repacking a Switch." |
Check the contents of the accessories box against the Accessories Box Components Checklist and the packing slip. Verify that you received all listed equipment, which should include the following:
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, with a minimum depth (between the front and rear mounting posts) of 19.25 inches (48.9 cm) and a maximum depth of 32 inches (81.3 cm). This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the switch.
The following tools and equipment are required to install the chassis:

The following tools and equipment are required to install the chassis in a rack:
To install Catalyst 2948G and 2980G switches in a rack, follow these steps:
a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.
b. Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The depth must be at least 19.25 inches (48.9 cm) but not greater than 32 inches (81.3 cm).
c. Measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (The chassis is 17.5 inches [44 cm] wide and must fit between the mounting posts.)
d. Open the rack-mount kit and refer to the component checklist in Table 3-1 to verify that all parts are included.
| Quantity | Part Description |
|---|---|
2 | L brackets |
4 | M4 Phillips pan-head screws |
4 | 12-24 x 3/4-inch Phillips binder-head screws |
|
Note Figure 3-1 illustrates how to attach the front of the switch to the rack. You can also attach the rear of the switch to the rack, depending on the configuration of your rack. |
Step 2 Note that the L brackets connect the 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 Some equipment racks provide 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. |
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).
|
Note The Catalyst 2948G switch is shown in the rack-mounting illustrations. The rack-mounting procedure for the Catalyst 2980G switch is the same. |
Step 3 Install the chassis in the rack as follows:
a. Position the chassis in the rack as follows (see Figure 3-2):
b. Align the mounting holes in the L bracket with the mounting holes in the equipment rack.
c. Secure the chassis using six (three per side) 12-24 x 3/4-inch screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.
d. Use a tape measure and level to ensure that the chassis is installed straight and level.
Follow these steps to connect power to Catalyst 2948G and 2980G switches:
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 or other system problem, see "Troubleshooting the Installation," for troubleshooting information.
The console and Ethernet management ports are located on the front panel of the Catalyst 2948G and 2980G switches and are shown in Figure 1-1 and Figure 1-2. The console and Ethernet management ports use an RJ-45 media-dependent interface crossed-over (MDIX) connector (see Figure 3-3). See "Specifications," for port pinouts.
|
Note The MDIX 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. |
