Equipment Rack Guidelines
The placement of racks can affect personnel safety, system maintenance, and the system
’
s ability to operate
within the environmental characteristics described in the above tables. Choose a proper location for the Cisco
ASR 1001-X Router by following the guidelines below.
Locating for Safety
If the Cisco ASR 1001-X Router is the heaviest or the only piece of equipment in the rack, consider installing
it at or near the bottom to ensure that the rack
’
s center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, see the document GR-63-CORE,
Network Equipment Building System (NEBS) Requirements: Physical Protection.
Locating for Easy Maintenance
Keep at least 3 feet of clear space in front of and behind the rack. This space ensures that you can remove the
Cisco ASR 1001-X Router components and perform routine maintenance and upgrades easily.
Avoid installing the Cisco ASR 1001-X Router in a congested rack and consider how the routing of cables
from other pieces of equipment in the same rack might affect access to the routers cards.
The front and top of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating
inside the chassis.
Allow the following clearances for normal system maintenance:
•
At the top of the chassis
—
At least 3 in. (7.6 cm)
•
In front of the chassis
—
3 to 4 ft (91.44 cm to 121.92 cm)
To avoid problems during installation and ongoing operation, follow these general precautions when you plan
the equipment locations and connections:
•
Use the
show environment all
and the
show facility-alarm status
command regularly to check the
internal system status. The environmental monitor continually checks the interior chassis environment;
it provides warnings for high temperature and creates reports on any occurrences. If warning messages
are displayed, take immediate action to identify the cause and correct the problem. For more information
on these commands, see the
Environmental Monitoring and Reporting Functions
.
•
Keep the Cisco ASR 1001-X Router off the floor and out of the areas that collect dust.
