Chapter 2 Preparing the Cisco uBR7225VXR Router for Installation

Site Preparation Checklist

•Install and use the cable-management bracket included with the Cisco uBR7225VXR rack-mount kit to keep cables organized. Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the interface slots, or require you to disconnect cables unnecessarily to perform equipment maintenance or upgrades.

In addition to the preceding guidelines, review the precautions for avoiding overtemperature conditions in the “Site Environment” section on page 2-5. To properly install the Cisco uBR7225VXR router chassis in a rack, refer to the instructions in the “Cisco uBR7225VXR Router Chassis Rack-Mounting Options” section on page 3-2.

Caution Do not install the Cisco uBR7225VXR chassis in an enclosed rack or room that is not properly ventilated or air-conditioned. The Cisco uBR7225VXR chassis overheats if the input air temperature reaches 105oF (41oC).
