General Rack Selection Guidelines; Guidelines For 23 In. (Telco) Racks - Cisco ASR 1013 Hardware Installation Manual

Rack-Mounting Guidelines
• Ensure that the rack is level and stable before extending a component from the rack.
• Ensure that proper airflow is provided to 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 1000 Series 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, then install the stabilizers before mounting or servicing
the unit in the rack.

General Rack Selection Guidelines

Cisco ASR 1000 Series Routers 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. equipment racks.
Consider installing the Cisco ASR 1000 Series 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 1000 Series 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 1000 Series 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.

Guidelines for 23 in. (Telco) Racks

If needed, you can also install the Cisco ASR 1000 Series Routers in 23 in. (Telco) racks. For information on
adapters needed for 23 in. racks, please contact the Newton Instrument Company:
