Terminal. If the problem persists (see “Troubleshooting” on page 171).

Troubleshooting a Base Station
1.
Verify that the green LED (the power indicator) is on.
2.
Verify that the red light is not solid.
A solid red light indicates that both radios on the Base Station are busy

downloading data to the Base Stations, or that the radios have not been
assigned to a cell.
3.
Verify that the red light is not flashing.
The red LED flashes for about 15 seconds when a Base Station is
powered up. This is normal. If the red LED continues to flash, then one
of the following problems may exist:
•
The Base Station is not connected to the Controller or line card.
•
The wiring to the Base Station is not correct. Check for open circuits
through the secondary protectors for applications with exposed wiring.
•
The two-way DC loop resistance of the power pair(s) between the RPI
and the Base Station exceeds 100
Ω
. Measure the loop resistance with an
ohmmeter. If the resistance exceeds 100
Ω
, install a second power pair.
•
The Base Station or RPI is faulty.
If the red LED is flashing on multiple Base Stations, one of the following
problems may exist:
•
The CMCC, CMRC, or CMBC card associated with the Base Stations
may not be in place.
•
The MDF cable may have been removed.
4.
Verify that the power cord of the RPI is properly connected to a working
AC outlet. If the Base Station is powered locally, verify that the power
