APPENDIX D: TROUBLESHOOTING QUICK GUIDE

 

 

Alarm list:

 

 

 

 

Figure 33: Alarm list 

 

Troubleshooting:

 

 

 

 

 

 

 

Over temperature

 

 

 

Environment temperature shall be lower than 140degF (60degC) 

PLL

 

(Phase lock loop)

 

Hardware failure, RMA the equipment 

LNA

 

(Low noise amp.)

 

Hardware failure, RMA the equipment 
1.  Handling RF connectors when RF power is ON may damage LNA 
2.  High power injection to DT/MT port may damage LNA 

 

DL PA

 

(Downlink amp.)

 

Fix any other existing alarms first, then reset PA (see next page) 
If alarm still exists, RMA the equipment 

 

 

Shutdown

 

Other critical alarm causes the equipment shutdown 
Follow instructions to fix other alarms first 

 

High input 
(for DT port)

 

Check input power to DT port, the power shall be lower than -30dBm 
1.  Avoid other inference 
2.  Put attenuator between antenna and PS BDA, if donor signal is high 

 

Antenna Malfunction 

Dry contact alarm 

Low Input alarm 

 

   

 

 

VSWR alarm 

 

 

 

Signal Booster Failure 

Dry contact alarm 

  

Over Temperature alarm 

   

 

 

 

PLL alarm 

 

 

 

LNA alarm 

 

 

 

DL PA alarm 

 

 

 

Shutdown alarm 

 

 

 

High input alarm 

 

 

Alarms

 

Causes and actions

 

 

Low input 
(for DT port)

 

DT composite input power lower than -80dBm will trigger the alarm 
1.  Donor antenna/passive system failure 
2.  Wrong channel frequency setting 
3.  Site is not commissioned yet 

VSWR 

Service antenna/passive system failure
