If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant
wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality
twisted-pair cable with one ground conductor for each data signal.
Lightning and AC Power Fault Interference
If signal wires exceed recommended cabling distances, or if signal wires pass between buildings, you should
consider the effect that a lightning strike in your vicinity might have on the Cisco ASR 1001-HX Router and
Cisco ASR 1002-HX Router.
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-HX Router and Cisco
ASR 1002-HX 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-HX Router or Cisco ASR 1002-HX 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-HX Router and Cisco ASR 1002-HX 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
exceed 131°F (55°C).
