Installing the Chassis in a Rack
You install the chassis in the equipment rack by setting the chassis in position
against the rack rails and then securing it to the rack or optional center-mounting
brackets with screws through holes in the rack-mounting flanges on either side of
the chassis.
To accommodate racks with different hole patterns in their rails, the chassis
rack-mounting flanges have two groups of eight oblong screw holes on either side
as shown in
Figure 3-4 . The mounting holes in the chassis flanges are spaced so
that one mounting hole in each hole group aligns with a hole in the rack rail or
optional center-mounting bracket. By using the corresponding mounting hole (in
the same hole group) on the opposite side of the chassis, you can level the chassis
in the rack.
Warning Two or more people should install the router to minimize the risk of personal
injury and damage to the equipment.
Refer to Figure 3-4 and use the following procedure to install the chassis in a rack.
Step 1 Move the router as close to the installation location as possible without interfering
with the installation process.
Step 2 With one person lifting from the front and one from the rear of the chassis, lift the
chassis off the pallet and position the chassis in the rack.
Note A third person might be needed to assist in lifting and positioning the
chassis in the rack.
Step 3 Install the screws to secure the chassis to the rack:
a. Look at the bottom mounting holes on the chassis rack-mount flanges. Align
one of the holes with a mounting hole in the rack.
b. Install one of the mounting screws provided.
c. On the other side of the chassis, adjust the position of the chassis so that the
same mounting hole in the bottom group of mounting holes is aligned with a
hole in the rack.
d. Install one of the mounting screws provided.
