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 105
o
F
(41
o
C).

Before installing the Cisco uBR7225VXR router, assemble the equipment needed to support your
