3.2 Alarms
Table 3-2 Alarms Threshold
Parameters Remark
AC Fail
Power supply is not operating within specs. (4 seconds)
DC Fail
Power supply is not operating within specs. (4 seconds)
Fan1, Fan2 Fail
System has detected an issue with each 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 20A]
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)
OSC
Oscillation detected. Alarm is only present when one-time
oscillation check is performed.
DL Signal not detected DL signal is below the specified level. (default: -90dBm, 4 seconds)
DL Signal Low DL signal is below the specified level. (default: -85dBm, 4 seconds)
Input Overload
Input signal is above the threshold. (4 seconds)
(Soft: DL -10dBm/UL -12dBm, Hard: DL -8dBm/UL -10dBm)
Out of band Overload
Out of band signal is above the threshold. (4 seconds)
(Soft: DL -10dBm/UL -12dBm, Hard: DL -8dBm/UL -10dBm)
Synthesizer Lock Fail
Issue with internal PLL(4 seconds)
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
AGC On case(Soft: AGC Level+ 1~2dB, Hard: AGC Level + >2dB)
AGC Off case(Soft: max output level+ 1~2dB, Hard: max output
level + >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.(Triggered in case of over +15dBm output power)
Door
