Rack-Mounting the Catalyst 4900M Switch
Follow these steps to install the Catalyst 4900M switch in a four-post rack.
Step 1 Prepare for installation:
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 19.0
inches (48.2 cm) but not greater than
28
inches (71.1 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 to verify that
all parts are included.
Note Figure 3-2 illustrates how to attach the front of the switch to the rack. You
will also need to attach the rear of the switch to the 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.
