Figure 8-18 Power & Gain Display (User)
x Input [dBm]: Displays the Downlink RF input level which comes from the ADX-H-BCU or BTS. This value should
be between 0 to 25 dBm.
x ALC Atten [dB]: The amount of attenuation that is being used by the system when ALC is active.
x Atten [dB]: The amount of attenuation that has been set manually by the user.
x Output [dBm]: The downlink/uplink output power of the RFU and NOT the output power of the RU.
8.2.2.3.3 Alarm
Displays System, RF, and Power Alarms. If an alarm is present in the system, then the color of the tab will
change according to the type of failure.
Table 8-8 RFU Alarm Status
Alarm Severity Description
System
Link Fail Soft Fail
A component is physically connected, but the
NMS is unable to communicate with it.
Over Temperature
Hard Fail /
Soft Fail
The temperature of NMS is higher than the
threshold level for over temperature alarm.
Under Temperature Soft Fail
The temperature of NMS is lower than the
threshold level for under temperature alarm.
System Halt
Hard Fail
System will go into a “System Halt” state when a
hard fail alarm does not clear after 10 checks.
System Halt can only be cleared with a power
cycle, reboot, or factory settings.
RF Alarm
DL Signal not detected
Soft Fail
Downlink input signal is lower than the defined
threshold by user.
DL Signal Low Soft Fail
Downlink input signal is lower than the defined
threshold by user.
Input Overload
Hard Fail /
Soft Fail
Downlink input signal is higher than the defined
threshold.
Overpower
Hard Fail /
Soft Fail
Uplink output signal is higher than the defined
threshold by user.
Power Alarm
AC Fail Soft Fail
AC power is not operating within parameters.
DC Fail Soft Fail
DC power is not operating within parameters.
Over Current
Hard Fail
Total current of HE is higher than the threshold
level for over current alarm.
Battery Low Soft Fail
Voltage
of battery connected to HE PSU is lower
than the defined threshold.
