Equipment Rack Guidelines
The placement of the rack can affect personnel safety, system maintenance, and the system ability to
operate within the environmental characteristics described in
location for the Cisco 1000 Series Router by following the guidelines below.
Locating for Safety
If the Cisco 1000 Series 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 center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, consult 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 and behind the rack. This space ensures that you can remove
the Cisco 1000 Series Router components and perform routine maintenance and upgrades easily.
Avoid installing the Cisco 1000 Series Router in a congested rack and consider how the routing of cables
from other pieces of equipment in the same rack could 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 the front of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)
When installing the Cisco ASR 1013 chassis in a 42RU equipment rack, allow at least one to two
inches (2.54 cm to 5.08 cm) of vertical clearance between the router and any equipment above
or below it.
Use the show environment all 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.
Keep the Cisco 1000 Series Router off of the floor and out of areas that collect dust.
Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
