Before installing the Cisco uBR7225VXR router, have all additional external equipment and cables
available. The information listed above is available at Cisco.com. For ordering information, contact a
customer service representative.

Equipment Racks

The rack-mounting hardware included with the Cisco uBR7225VXR universal broadband router is
suitable for most 19-inch equipment racks and telco-type racks. To easily access field-replaceable units
(FRUs) while the router is installed in a rack, ensure that 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 impairs a rear rack-mount installation, remove the power strip
before installing the Cisco uBR7225VXR router in the rack, then replace it after the chassis is installed.
As an alternative, you can mount the Cisco uBR7225VXR router on an equipment shelf if 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 uBR7225VXR router.

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 17.5 inches (44.45 cm).
The height of the Cisco uBR7225VXR chassis is 3.5 inches (8.89 cm).
When mounting the router in four-post or telco-type racks, be sure to use all the screws and the
brackets provided to secure the chassis to the rack posts.
