RA
Red
Radio Alarm
LED indicates problems with radio unit.
The following problems cause the Radio Alarm to turn on:
−
Rx signal level is lower the predefined value, - the
corresponding parameter is
RxAlarmLev
on the LCD or
RxAlarmLevel
using Telnet/ASCII console. The default value
for this parameter is -77 dBm;
−
The humidity within the radio is too high (possibly ODU is
opened);
−
Transmitter malfunction (TxOut=Error)
−
RF Cable=Short – cable is faulty, RF Cable=Off – cable or
Radio is faulty;
−
Tx and Rx syntheser loops are not locked (TxPLL=Error,
RxPLL=Error)
If not lit – operating properly (Rx=OK & TxOut=OK &
Humidity=Low & RF Cable – OK & TxPLL=OK & RxPLL=OK);
The RA LED will also switch on if the Radio loopback is active
and/or if the transmitter power is switched off.
The RA LED is updated one time per second.
SL
Red
Red Sync Lost LED indicates the multiplexer has lost
synchronization;
