Chapter 2 Preparing for Installation

Site Planning

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 the 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 903 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 and EMI experts to ensure that you have adequate electrical surge suppression and shielding of signal cables in your Cisco ASR 903 Router operating environment.

Rack-Mounting Guidelines

The following sections provide guidelines for rack-mounting the Cisco ASR 903 Router:

•Precautions for Rack-Mounting, page 2-15

•Rack Selection Guidelines, page 2-15

•Equipment Rack Guidelines, page 2-16

Precautions for Rack-Mounting

The following rack-mount 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 on or stand on any component or system when servicing other systems or components in a rack.

•When mounting the Cisco ASR 903 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.

Rack Selection Guidelines

The Cisco ASR 903 Router can be mounted in most two-post or four-post, 19-inch equipment racks that comply with the Electronic Industries Association (EIA) standard for equipment racks (EIA-310-D 19-inch). 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 65 degrees C.
