Table 23: Site Electrical Wiring Guidelines
Guidelines
Site Wiring Factor
If your site experiences any of the following problems, consult experts in electrical surge
suppression and shielding:
•
Improperly installed wires cause radio frequency interference (RFI).
•
Damage from lightning strikes occurs when wires exceed recommended distances or
pass between buildings.
•
Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and
electronic devices.
Signaling limitations
To reduce or eliminate RFI from your site wiring, do the following:
•
Use a twisted-pair cable with a good distribution of grounding conductors.
•
If you must exceed the recommended distances, use a high-quality twisted-pair cable
with one ground conductor for each data signal when applicable.
Radio frequency
interference
If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly
from lightning or radio transmitters, seek expert advice.
Some of the problems caused by strong sources of electromagnetic interference (EMI)
are:
•
Destruction of the signal drivers and receivers in the device
•
Electrical hazards as a result of power surges conducted over the lines into the equipment

Clearance Requirements for Airflow and Hardware Maintenance on
ACX2000 and ACX2100 Routers
When planning the installation site, allow sufficient clearance around the rack (see
):
•
For service personnel to remove and install hardware components, allow at least 2.16 in. (5.5 cm) in
front of the router.
•
The rack or cabinet must have an adequate supply of cooling air.
•
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating
into the router.
•
When deploying the router in harsh environments where the router may operate between 131° F (55°
C) and 149° F (65° C), allow a 1–rack unit (U) gap above and below the router.
•
Ensure that there is a minimum 1 meter/second airflow in any direction.
