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
