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.

Warning
Only trained and qualified personnel should be allowed to install or replace this
equipment.
Ultimate disposal of this product should be handled according to all national laws and
regulations.
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.
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.
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.
