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

cause:
• Radio interference emanating from the wires.
• Strong EMI, especially when caused by lightning or radio transmitters. EMI can destroy the signal drivers
Note
To predict and remedy strong EMI, you may need to consult with radio frequency interference (RFI) experts.
