Rack-Mounting the Catalyst 2948G and 2980G Switches
To install Catalyst 2940G and 2980G switches in a 19-inch rack, follow these
steps:
Step 1 Prepare for installation as follows:
a. Place the chassis on the floor or on a sturdy table, as close as possible to the
rack. Leave enough clearance to allow yourself to move around the chassis.
b. Use the 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) and 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. See
Figure 3-2.)
d. Open the rack-mount kit and refer to the component checklist in Table 3-1 to
verify that all parts are included.
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).
