Parameters
Remark
AC Fail
Power supply is not operating within specs. (4 seconds)
DC Fail
Power supply is not operating within specs. (4 seconds)
Fan Fail
System has detected an issue with the fan. (4 seconds)
Temperature
Module is above the normal operating temperature. (4 seconds)
Over Temperature [ Soft: 80~87 C, Hard: Above 87 C]
Current
Power supply is not operating within specs. (4 Second)
Over Current [ Hard: Above 10A]
System Halt
System is in a shutdown state due to a hard fail alarm. (10 times)
DSP Fault
System has detected an issue with the internal DSP chip. (Cannot
communication with DSP)
Link Fail
Communication error between the module and NMS. (5 mins)
BRS Out of Sync
Unable to perform TDD sync (10 seconds)
OSC
Oscillation detected. Alarm is only present when one-time
oscillation check is performed (4 seconds)
DL Signal not detected
DL signal is below the specified level. (default: -85dBm)
DL Signal Low
DL signal is below the specified level. (default: -90dBm)
Input Overload
Input signal is above the threshold.
(Soft: -17dBm, Hard: -15dBm)
Out of band Overload
Out of band signal is above the threshold.
(Soft: -17dBm, Hard: -15dBm)
Synthesizer Lock Fail
Issue with internal PLL
DL RF Power
Input + gain does not match the output level
(default delta of 6 dB)
Overpower
Output level is above the max output levels
(Soft: ALC or AGC + 1~2dB, Hard: ALC or AGC + >2dB)
VSWR
Power is being reflected back to the repeater. Threshold = output
power - 8dB. For example, if the repeater is outputting 24dBm,
then if the system detects 16dBm of return power, then the VSWR
will be triggered.
