system, unplug the power cord, disconnect any cables at the ports, and connect your ESD-preventive
wrist strap.
Old and New Versions of Chassis Shell
Cisco 4000 series routers have two chassis versions. (See Figure 1.) In the old version of the chassis,
the rack-mount and wall-mount brackets are secured to the chassis with tabs located on the inside of
the chassis shell. Newer versions of the chassis use screws to attach the brackets to the side of the
chassis shell. The rack-mount and the wall-mount brackets supplied with this kit can be used with
both types of chassis.
Figure 1
Preparing the Chassis for Rack-Mounting or Wall-Mounting
To rack-mount or wall-mount the chassis, you must first remove the front panel and component tray
from the chassis shell.
Some Cisco 4000 series routers have a safety latch tab on the chassis that affects removing the
component tray. (See Figure 2 and Figure 3.)
If you have a chassis with a safety latch tab, follow the procedure in the following section,
"Removing the Component Tray from a Chassis with a Safety Latch."
If you have a chassis without a safety latch tab, follow the procedure in the section "Removing the
Component Tray from a Chassis without a Safety Latch," later in this document.
