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 Before working on equipment that is connected to power lines, remove je welry (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.

2 Cisco 4000 Series Rack-Mount and Wall-Mount Installation

— Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

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.

Cisco 4000 Series Rack-Mount and Wall-Mount Installation 3

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 an y cables at the ports, and connect your ESD-preventi ve
wrist strap.

Old and New Versions of Chassis Shell

Cisco 4000 series routers have two chassis versions. (See Figure 1.) In the old v ersion 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.

Preparing the Chassis for Rack-Mounting or Wall-Mounting

T o rack-mount or wall-mount the chassis, you must first remov e 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.

Mounting the Chassis Shell on a Wall

Note The chassis should be wall-mounted with the front and rear of the chassis perpendicular to

the floor and at eye level, so you can read the front and rear LEDs. All four mounting screws must
be anchored to solid wood.

Step 3 Lay the chassis on top of a plywood board (19 x 19 x 1/2 inch minimum, not supplied).

Using the chassis as a pattern, mark or drill the wall-mount screw locations on the board.
T o make inserting the scre ws easier, drill the screw locations before you mount the chassis.

Step 4 T o safely accommodate variations in interior wall construction, locate the wall studs (2 x 4"

boards inside a building’ s walls, commonly spaced 16 inches apart) and attach the plywood
board securely to the wall, nailing the board to the studs.

Step 5 Start the two screws that will be used to fasten the bottom bracket in their places on the

bottom of the board, leaving at least 1/4 inch of each screw exposed.

Step 6 Insert the lower bracket into the two wood scre ws you just placed on the piece of plyw ood

(see Figure 14 or Figure 15). While continuing to support the chassis shell, insert one wood
screw through the top wall-mount bracket to hold the chassis in place. Follow this by
inserting the second wood screw into the top wall-mount bracket.

Step 7 Tighten all wood screws.
Step 8 Reinsert the component tray into the shell.
Step 9 Push on the back of the tray while at the same time pressing on the chassis release screw

(shown in Figure 2 and Figure 3) with the thumb of your right hand.

Step 10 Retighten the chassis release screw.

This completes the wall-mount procedure.
