CPE RF Surge Protector
Table 4: CPE RF Surge Protector Specifications
6.8.3. Power-Over-Ethernet Surge Protection
Up tower radios, including the CPE, should have primary lightning
protection installed at both ends of the POE line if the wiring
travels outside or between buildings. It is critical to install primary
protection at the customer end of the wiring to prevent possible
electrocution of the customer when lightning strikes near the
equipment. If the radio is not powered, the Ethernet and RF
connections should be disconnected to protect the circuitry.
