Installing The Chassis; Rack-Mounting The Chassis - Cisco 3640 Quick Start Manual

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 RJ-45 connectors. Use caution when connecting cables. Statement 1021
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if
you are uncertain that suitable grounding is available. Statement 1024
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages
and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards,
faceplates, front covers, and rear covers are in place. Statement 1029
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on
modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight
of the unit. Statement 1032
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

Installing the Chassis

You can set the chassis on a desktop or install it in a rack. A Cisco 3620 chassis can also be mounted on a wall or other flat
surface. See the applicable instructions following.
Caution To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always
hold the chassis by the metal body.

Rack-Mounting the Chassis

The standard accessory kit contains brackets for mounting the chassis in a 19-inch rack. You can order an optional accessory
kit with brackets and instructions for mounting the chassis in a 23- or 24-inch rack.
You can mount the chassis in the following ways:
• Front panel forward
• Rear panel forward
• In a center-mount telco rack (Center-mounting of Cisco 3640 routers is restricted to 19-inch telco racks and requires the
use of the center-mount bracket in the optional NEBS/ETSI compliance kit.)
Note The rubber feet that are supplied in the accessory kit of the Cisco 3620 are not needed for installation in a rack.
