Installation guide

Configuring the Cisco 4000 Series Chassis 3-9
Replacing the Component Tray
Step 3 Replace the module mounting screw in its place on the end of the network
processor module. (See Figure 3-4.)
Caution Do not overtighten the module mounting screw. The network processor module
or the underlying motherboard could be damaged. The maximum screw torque is 7 inch-lb.
Step 4 Replace the external rear mounting screws, if used, to attach the module to the rear
of the chassis.
Replacing the Component Tray
Take the following steps to replace the component tray in the chassis shell:
Step 1 Reinsert the component tray into the chassis shell, pushing on the back of the tray
while at the same time pressing on the chassis release screw with the thumb of
your right hand. (See Figure 3-2.)
Step 2 Retighten the chassis release screw.
Rack-Mount and Wall-Mount Installation
You can use optional rack-mount and wall-mount kits to install a Cisco 4000 series router
in a standard 19-inch rack, a 19-inch telco rack, or on a wall. The procedures for the
different installation options involve removing the front panel and component tray from the
chassis, fastening mounting brackets to the chassis, and then installing the empty chassis in
position. You then reinsert the component tray and replace the front panel.
The optional rack-mount and wall-mount kits ship with their own set of installation
instructions. If you are planning to rack-mount or wall-mount the router, do so before
making the network and power connections.
