you might want to seek expert advice. Strong sources of electromagnetic interference
(EMI) can destroy the signal drivers and receivers in the router and conduct power
surges over the lines into the equipment, resulting in an electrical hazard. It is particularly
important to provide a properly grounded and shielded environment and to use electrical
surge-suppression devices.
CAUTION: To comply with intrabuilding lightning and surge requirements,
intrabuilding wiring must be shielded, and the shield for the wiring must be
grounded at both ends.
