Before installing the Cisco 7204, have all additional external equipment and cables on hand. The
information listed above is contained in the documentation that is shipped with each port adapter. For
example, if you need ATM distance limitations and pinouts, refer to the configuration note PA-A3
Enhanced ATM Port Adapter Installation and Configuration. This configuration note accompanies each
PA-A3 enhanced ATM port adapter that is shipped from the factory as an installed item in a Cisco 7204
and as a FRU.
For ordering information, contact a customer service representative.
Equipment Racks
The rack-mounting hardware included with the Cisco 7204 is suitable for most 19-inch equipment racks
and telco-type racks. To easily access FRUs while the router is installed in a rack, make certain you have
access to the front and rear of the router.
Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power
strip before installing the Cisco 7204 in the rack, then replace it after the chassis is installed. As an
alternative, you can mount the Cisco 7204 on an equipment shelf provided that the rack dimensions
allow you to secure the router to the shelf, and the overall configuration permits safe installation and
access. However, we recommend rack-mounting the Cisco 7204. shows the Cisco 7204 footprint and
outer dimensions.
To use the rack-mounting hardware provided with the Cisco 7204, consider the following guidelines:

Any additional interface equipment you need, such as transceivers, hubs, switches, modems,
channel service units (CSUs), or data service units (DSUs)
Cable pinouts if you plan to build your cables
To mount the router between two posts or rails using the brackets, the inner clearance (the width
between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm).
The height of the chassis is 5.25 inches (13.34 cm).
When mounting the router in 4-post or telco-type racks, be sure to use all the screws and brackets
provided to secure the chassis to the rack posts.
