Cisco 7204 Installation and Configuration Guide
2-10
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.
The Cisco 7204 installation must comply with all applicable codes and is approved for use
Note
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

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

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
7204.")
