Cisco ASR 1001-X Router Hardware Installation Guide

Chapter 3 Preparing Your Site for Installation
Site Planning
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple
enough energy into unshielded conductors to damage or destroy electronic equipment. If you have
previously experienced such problems, you should consult with RFI/EMI experts to ensure that you have
adequate electrical surge suppression and shielding of signal cables in your Cisco ASR 1001-X Router
operating environment.
Rack-Mounting Guidelines
This section describes guidelines on rack-mounting.
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.
Caution When mounting a chassis in any type of rack equipment, ensure that the inlet air to the chassis does not
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.
