Guidelines
Site Wiring
Factor
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 for an
ACX5000 Router
When planning the site for installing an ACX5000 router, you must allow sufficient clearance around the
installed chassis (see Figure 26 on page 81).
