Site Wiring Guidelines

When planning the location of the router, consider distance limitations for signaling, electromagnetic
interference (EMI), and connector compatibility. If the wiring is run for any significant distance in an
electromagnetic field, interference can occur between the field and the signals on the wires. Poor wiring can
cause:
• Radio interference emanating from the wires.
• Strong EMI, especially when caused by lightning or radio transmitters. EMI can destroy the signal
drivers and receivers in the router, and can even create an electrical hazard by conducting power surges
through lines and into equipment.
