Chapter 3 Installing the Router
Rack-Mounting the Router Chassis
Installing the Chassis Rack-Mounting Platform
The rack-mounting platform is installed at the bottom of an empty rack and acts
as a permanent support platform for the chassis. It can be installed in either the
front-mounted position or the center-mounted position, to match the installed
position of the chassis.
The platform is adjustable from a minimum height of 5.25 inches (13.34 cm) to a
maximum height of 8.00 inches (20.32 cm). For telco-style racks, the bottom
edge of the platform can be raised to approximately 6.00 inches (15.24 cm) to
clear the cross-members at the bottom of the rack.
Warning The chassis should be mounted on a rack that is permanently affixed to the
building
Use the following procedure to install the rack-mounting platform.
Step 1
Remove the platform from the accessory box.
Step 2 Adjust the height of the platform to match the required rack-mounting height for
the chassis:
a.
Turn each of the adjustable feet to approximately the required platform height
(
Figure 3-6 ).
b.
Place the platform in the rack making sure that it clears any rack
cross-members.
c. Use a level to be sure the platform is level from side to side and front to back.
d.
Adjust the feet until the platform clears any obstacles and is level at the
required platform height.
Step 3
Determine whether the platform is to be installed in the front-mounted position or
in the center-mounted position, and adjust the positioning brackets on the
platform:
a. Locate the hole on the side of the platform that corresponds with the
front-mounted or center-mounted position of the table.
b.
Align the side of the bracket with the round hole over the hole on the side of
the platform, insert a screw, and use your fingers to loosely tighten it (see
blow-out in
Figure 3-6 ).
