CAUTION
Surge suppressors should be installed on any cables where they enter a building to
reduce the possibility of over voltages or over currents damaging any equipment in
the building.
The following equipment, mounted outside of a communications hut or building at the point
where the cables penetrate the building, is recommended:
•
Motorola 600SSD surge suppressors for Ethernet cables
•
Motorola 200SS surge suppressors for DC cables
•
A PolyPhaser DGXZ+06NFNF-A surge suppressor for the coaxial cable from the GPS
antenna
Power Faults
If excessive current is drawn on a port, the analog circuitry reports a PoE fault. The system then
turns the port power off. The power will be restored when the fault is removed. The following
illustration shows the port status screen with a power fault on port 1.
