Center-Mount Bracket Installation Guide for
Cisco 3640 Routers
This document provides instructions for use of center-mount brackets for rack mounting of Cisco 3640
routers.
The center-mount bracket provides enhanced solidarity for router chassis mounted in standard 23-inch
telco racks. This mounting system assures earthquake safety for rack-mounted routers.
The center-mount bracket kit contains one pair of brackets and 12 screws for attaching the brackets to
the router chassis. The two brackets are identical, and each bracket can be mounted on either side of the
router chassis.

Varning!Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till
personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med
elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar som
förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information
(Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.
Warning Only trained and qualified personnel should be allowed to install or replace this
equipment.
Warning Ultimate disposal of this product should be handled according to all national laws and
regulations.
Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to
user contact. Do not attempt to tamper with or open any public telephone operator
(PTO)-provided equipment or connection hardware. Any hardwired connection (other
than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or
suitably trained engineers.
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN
ports contain TNV circuits. Some LAN and WAN ports both use common connectors. Use
caution when connecting cables.
Warning Hazardous network voltages are present in WAN ports regardless of whether power to
the router is OFF or ON. To avoid electric shock, use caution when working near WAN
ports. When detaching cables, detach the end away from the router first.
Warning Do not work on the system or connect or disconnect cables during periods of lightning
activity.

Safety Recommendations
Caution NEBS/ETSI Intrabuilding Lightning Requirement
This equipment is suitable for connection to intrabuilding or nonexposed wiring or cabling
only. This cabling must be shielded.
General Safety Practices
Follow these guidelines to ensure general safety:
•Keep the chassis area clear and dust-free during and after installation.
•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 equipment unsafe.
Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
Warning Before working on equipment that is connected to power lines, remove jewelry
(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.
•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.
•Disconnect all power before installing or removing a Cisco router chassis
•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 chassis.
– 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.
