Chapter 2 Preparing the Cisco uBR7200 Series Router for Installation
Provisioning the Cable Headend
•
If you use telco-type racks, be sure that the rack is bolted to the floor and secured, because in these
types of installations, only one end of the chassis mounts to the two rack posts with the brackets.
Ensure that the weight of the chassis does not make the rack unstable.
•
Install and use the cable-management bracket included with the Cisco uBR7200 series rack-mount
kit to keep cables organized and out of the way of the port adapters and I/O controller. Consider the
equipment and cabling that is already installed in the rack. Ensure that cables from other equipment
will not impair access to the port adapters, or require you to disconnect cables unnecessarily to
perform equipment maintenance or upgrades.
•
You cannot install the cable-management bracket on a Cisco uBR7200 series router that you have
mounted from the front.
In addition to the preceding guidelines, review the precautions for avoiding overtemperature conditions
in the
“Site Environment” section on page 2-6
. To properly install the Cisco uBR7200 series router
chassis in a rack, refer to the instructions in the
“Cisco uBR7200 Series Chassis Rack-Mounting
Options” section on page 3-2
.
Caution
Do not install the Cisco uBR7200 series chassis in an enclosed rack or room that is not properly
ventilated or air-conditioned. The Cisco uBR7200 series chassis overheats if the input air temperature
reaches 105
o
F (41
o
C).
