5.2 Troubleshooting Guide for Repeater
Alarm Status Parameter Troubleshooting
VSWR Hard Fail VSWR Over 3:1
1. Make sure connectors are tight at each port.
Sweep lines.
2. Use a 50 Ω dummy load, connect it to the
Alarming Port to check whether the repeater
is faulty. (e.g. if the Down Link is alarming,
connect the dummy to the Server Port.)
3. If multiple Server Antennas are connected,
connect only one antenna and recheck the
Alarm. If the Alarm clears, faulty connectors
like combiners/ splitters in the serving line and
lightning arrestors (polyphasers) may be
causing the problem.
Over Power
Soft Fail UL/DL
Epoch-H(5Watt) 37dBm~38dBm
>Max Output
Power+1dB
1. Check Input/Gain/Output values in the
‘Status Page’
2. Check Input Level (If the input exceeds the
max rated power, add an Attenuator to the
input/ Donor port)
3. Check whether AGC is On (In the case of UL
Shutdown, make sure that Tracking is OFF)
4. Factory Setting & Reboot
Epoch-H(10Watt) 40dBm~41dBm
Epoch-H(20Watt) 43dBm~44dBm
Hard Fail UL/DL
Epoch-H(5Watt) 37dBm~39dBm
>Max Output
Power+2dB
Epoch-H(10Watt) 40dBm~42dBm
Epoch-H(20Watt) 43dBm~45dBm
RF Power Soft Fail Invalid Output Level of Gain
1. Check whether Input/Gain/Output are
invalid.
2. From the Control page, check the Alarm
Settings.
