Antistatic mat or antistatic foam in case you need to remove switch modules to
troubleshoot the installation
•
Your own ESD grounding strap or the disposable ESD strap included with the system
If you are installing the chassis in a rack, you will also need the following:
•
Rack-mount kit
•
Tape measure and level
Installing the L Brackets
The rack-mount kit is for a standard 19-inch rack with a minimum depth (between the front
and rear mounting posts) of 19 1/4 inches and a maximum depth of 32 inches. The width
between the two front equipment mounting strips (left front and right front) must be at least
17 3/4 inches. Two L brackets, which you attach to either the front or back of the chassis,
and the mounting posts connect the chassis to the rack. Some equipment racks provide a
power strip along the length of one of the rear posts. If your rack has this feature, consider
the position of the strip when planning fastener points, and before you install the L brackets
on the chassis, determine whether you will install the chassis from the front or the rear of
the rack.
Take the following steps to attach the two L brackets to the switch chassis:
Step 1
Step 2
Step 3
Step 4
Place the chassis on the floor or on a sturdy table as close as possible to the rack,
with clearance to allow you to move around the chassis.
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 1/4 inches, but not greater than 32 inches.
Measure the space between the inner edges of the left front and right front
mounting posts to ensure that it is 17 3/4 inches wide. (The chassis is
17 1/4 inches wide and must fit between the mounting posts.)
Open the rack-mount kit and refer to the component checklist in Table 3-1 to
verify that all parts are included.
