Rack-Mounting Guidelines

Precautions for Rack-Mounting

The following rack-mounting guidelines are provided to ensure your safety:
• Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two people
are required to accomplish this task.
• Ensure that the rack is level and stable before extending a component from the rack.
• Ensure that proper airflow is provided to the components in the rack.
• Do not step or stand on any component or system when servicing other systems or components in a rack.
• When mounting the Cisco ASR 1001-X Router in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.

General Rack-Selection Guidelines

The Cisco ASR 1001-X Router can be mounted in most two-post or four-post, 19-in. equipment racks that
comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D 19-in.).
The rack must have at least two posts with mounting flanges to mount the chassis.
When mounting a chassis in any type of rack equipment, ensure that the inlet air to the chassis does not
Caution
exceed 131°F (55°C).
The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 in. ±
0.06 in. (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most
19-in. (48.3-cm) equipment racks.
Consider installing the Cisco ASR 1001-X Router in a rack with the following features:
• NEBS-compliant, 19-in. (48.3-cm) wide rack.
• EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the Cisco
ASR 1001-X Router. If the rack that you plan to install the system in has metric-threaded rails, you must
provide your own metric-mounting hardware.
• Perforated top and open bottom for ventilation to prevent overheating.
• Leveling feet for stability.
The Cisco ASR 1001-X Router should not be installed in an enclosed rack because the chassis requires
Note
an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal
components. Installing the router in any type of enclosed rack—even with the front and back doors removed
—could disrupt the air flow, trap heat next to the chassis, and cause an overtemperature condition inside
the router. If you use an enclosed rack, make certain that there are air vents on all sides of the rack and
there is proper ventilation.
