Safety Recommendations
Note All warnings in this document appear in multiple languages in the appendix “Translated
Safety Warnings” in the Cisco 4000 Series Installation Guide.
Safety Recommendations
Follow these guidelines to ensure general safety:
•Keep the chassis area clear and dust-free during and after installation.
•Put the removed chassis cover in a safe place.
•Keep tools away from walk areas where you or others could fall over them.
•Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll
up your sleeves.
•Wear safety glasses when working under any conditions that might be hazardous to your eyes.
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
Safety with Electricity
Warning Beforeworkingonequipmentthat is connected to powerlines,removejewelry (including
rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and
can cause serious burns or weld the metal objects to the terminals.
Follow these guidelines when working on equipment powered by electricity:
•Locate the emergency power-off switch in the room in which you are working. Then, if an
electrical accident occurs, you can quickly shut the power OFF.
•Before working on the system, turn OFF the power and unplug the power cord.
•Disconnect all power before doing the following:
—Installing or removing a router chassis
—Working near power supplies
—Performing a memory upgrade
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
•If an electrical accident occurs, proceed as follows:
—Use caution; do not become a victim yourself.
—Turn OFF power to the system.
—If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim and then call for help.

Required Tools and Parts
—Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Required Tools and Parts
The following tools and parts are required for rack-mount and wall-mount procedures:
•Screwdriver, number 1 or number 2 Phillips
•Screwdriver, number 2 flat-blade
For wall-mounting, the following additional equipment is required:
•Plywood board (19 x 19 x 1/2 inch minimum size)
•Wood fasteners for attaching the board to the wall
Table 1 lists the parts contained in the standard rack-mount kit.
Table 1 Standard Rack-Mount Kit Components
Table 2 lists the parts contained in the telco rack-mount and wall-mount kit.
Table 2 Telco Rack-Mount and Wall-Mount Kit Components
Overview of Rack-Mount and Wall-Mount Procedures
The Cisco 4000 series routers can be mounted in a standard 19-inch rack, a telco 19-inch rack, or on
a wall. The procedures for the different mounting options involve removing the front panel and
component tray from the chassis shell and then installing the empty shell in position before
reinserting the component tray.

Preparing the Chassis for Rack-Mounting or Wall-Mounting
Warning Hazardous voltages may exist in or near the power supply, so use extreme caution when
working near the power supply. Before starting any of these procedures, turn OFF power to the
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 Old and New Versions of the Cisco 4000 Series Chassis Shell
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.

Warning Hazardous voltages may exist in or near the power supply, so use extreme caution when
working near the power supply. Before starting any of these procedures, turn OFF power to the
system, unplug the power cord, disconnect any cables at the ports, and attach your ESD-preventive
wrist strap.
Take the following steps to remove the component tray from a chassis with a safety latch:
Step 1 Turn OFF the system power.
Step 2 Attach your ESD-preventive wrist strap.
Step 3 Remove all network and power cables.
Step 4 Loosen the nonremovable screw in the back of the router chassis. The screw is labeled
“Chassis release screw” in Figure 2.
Figure 2 Component Tray Removal for Chassis With a Safety Latch
Warning Before releasing the safety latch, support the component tray from underneath either on
your work surface or with your hands to prevent it from falling (see Figure 2).
Step 5 Slide the component tray out of the chassis shell while facing the rear panel of the chassis,
pulling the handle on the right side of the chassis until the safety latch catches. (See
Figure 2.)
Step 6 Supporting the component tray with one hand, push down on the safety latch tab while you
pull out on the component tray.

Step 5 While facing the rear panel of the chassis, pull the handle on the right side of the router
while you support the component tray with one hand. Slide the component tray out of the
chassis shell.
Step 6 Set the component tray on your work surface.
Mounting the Chassis in a Standard Rack
After removing the chassis shell and front panel, you can install the standard rack-mount brackets
into the chassis shell. The standard 19-inch rack-mount kit (see Figure 4) consists of two sets of one
bracket, one short extender (approximately five inches) (see Figure 5), and one long extender
(approximately ten inches) (see Figure 6).
If you have an older version of the chassis, use the first of the following procedures to install the
standard rack-mount brackets. If you have a new version of the chassis, use the second procedure to
install the standard rack-mount brackets. After installing the brackets, use the third procedure to
install the chassis shell into a standard 19-inch rack.
Note The brackets provided with your kit fit both the early, tab-mount chassis shells and the newer
screw-mount chassis shells.
