This document describes how to rack-mount or wall-mount a Cisco 3620 or Cisco 3640 router.
Note In this document, the term “Cisco 3600 series” refers to the Cisco 3620 and Cisco 3640
routers.
Use this document in conjunction with your router installation and configuration guide and the
Regulatory Compliance and Safety Information document for your router.
If you have questions or need help, refer to the section “Obtaining Service and Support” later in this
document.

Safety Recommendations
Warning To ensure your safety and the safety of others, be sure the power is OFF and the power
cord is unplugged before working on the router. (To see translated versions of this warning, refer to
the Regulatory Compliance and Safety Information document that accompanied your router.)
Caution To avoid damaging electrostatic discharge (ESD)-sensitive components, ensure that you
have discharged all static electricity from your body before opening the chassis. Before performing
procedures described in this document, review the next section, “Safety Recommendations.”
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 Beforeworkingonequipmentthatis 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 object to the terminals. (To see translated versions of this
warning, refer to the Regulatory Compliance and Safety Information document that accompanied
your router.)
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 router, 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 software upgrade
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.

Cisco 3600 Series Rack-Mount and Wall-Mount Configuration Note 3
Rack-Mounting the Router
•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 router.
—If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim and then call for help.
—Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic printed circuit cards are improperly handled and can result in complete or intermittent
failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that
the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap,
ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis
frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage
and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be
between 1 and 10 megohms (Mohm).
Rack-Mounting the Router
This section explains how to mount a Cisco 3620 or Cisco 3640 router in a 19-inch, 23-inch, or
24-inch equipment rack or telco rack. If you have questions or need help with the rack-mounting
procedure, refer to the section “Obtaining Service and Support” later in this document.
If you are planning to rack-mount your router, do so before making network and power connections.
If you need to install network modules or WAN interface cards, you can do so either before or after
mounting the router, whenever you have better access to the rear of the router.
Required Tools and Equipment
You need the following tools and equipment to mount a Cisco 3600 series router in a rack:
•Number 2 Phillips screwdriver
•ESD-preventive wrist strap
•Screws for attaching the router to the rack (not supplied)
Each router is shipped with one set of brackets. Brackets for 19-inch racks are shipped unless you
specify 23-inch or 24-inch brackets at the time of your order. Figure 1 shows brackets for the
Cisco 3620 router, and Figure 2 shows brackets for the Cisco 3640 router.
