Power Considerations
Follow these precautions and recommendations when planning power connections to the Cisco 7204:
•
Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
•
Install proper grounding to avoid damage from lightning and power surges.
Note
The Cisco 7204 installation must comply with all applicable codes and is approved for use
with copper conductors only. The ground bond fastening hardware should be of compatible
material and preclude loosening, deterioration, and electro-chemical corrosion of hardware
and joined material. Attachment of the chassis ground to a central office or other interior
ground system should be made with a 6-AWG, copper ground conductor at a minimum. The
Cisco 7204 chassis employs two threaded M5 chassis grounding receptacles, located on the
rear of the chassis, which are intended to be bonded directly to the central offices or other
interior ground system. The chassis ground requires M5 screws and locking hardware, which
are not included. (For instructions on how to properly ground the chassis, refer to the
“Providing a Chassis Ground Connection for the Router Chassis” section on page 3-11
in
Chapter 3, “Installing the Cisco 7204.”

Tools for Installation
Your Cisco 7204 chassis is fully assembled at the factory; no assembly is required. However, you will
need the following tools and equipment to install the chassis and the rack-mount and cable-management
kit:
•
Number 2 Phillips screwdriver
•
3/16-inch flat-blade screwdriver
•
Tape measure (optional)
•
Level (optional)
The rack-mount and cable-management kit includes the following parts:
•
Two rack-mount brackets for mounting the chassis in the rack
•
Four M4 x 8-mm Phillips flathead screws to secure the rack-mount brackets to the chassis
•
Six 10-32 x 3/8-inch slotted binderhead screws to secure the rack-mount brackets to the rack rails
•
Two cable-management brackets to relieve the strain on installed port adapter interface cables
•
Four M4 x 8-mm Phillips flathead screws to secure the cable-management brackets to the chassis or
the rack-mount brackets
In addition, you might need the following external equipment:
•
Data service unit (DSU) to connect each serial port to an external network.
•
One serial port adapter cable for each serial port to connect the port with the remote device or
network.
•
To connect a serial port to a T1 network, you need a T1 channel service unit/data service unit
(CSU/DSU) that converts the High-Level Data Link Control (HDLC) synchronous serial data stream
into a T1 data stream with the correct framing and ones density. (Some telephone systems require a
