Alarm

Cause
Remedy
Input Upper-limit
- Blinking green while processing the
algorithm
- Blinking red while shutting down for
30 mins.
- Solid red while fully shutting down
This alarm is raised when input power
is over +3 dB than rated input power.
1.8 GHz : -19 dBm
3.5GHz : -21 dBm
①
Access to the LMT and check input power level.
②
If the power is strong, insert a suitable attenuator into
the coaxial cable between the antenna and the re-
peater.
※
Rated input power range
1.8 GHz : -52 to -22 dBm
3.5 GHz : -54 to -24 dBm
③
If the power is still strong, change the antenna location.
Output Upper-limit
- Blinking green while processing the
algorithm
- Blinking red while shutting down for
30 mins.
- Solid red while fully shutting down
This alarm is raised when output
power is over +3 dB than rated output
power.
1.8GHz : 15 dBm
3.5GHz : 21 dBm
①
Access to the LMT and check in/output status.
②
If the input power is normal but the output power
reaches up to upper-limit, check the device output up-
per-limit level is set correctly.
③
If the input power is strong, rotate a Donor Antenna di-
rection to decrease the power.
④
If the input power is still strong, change the antenna lo-
cation.
⑤
Measure the actual output power and verify the device
operates correctly.
⑥
If the device has a problem, replace the device.
Output Lower-limit
- Solid orange
This alarm is raised when output
power is being lower than lower-limit
for 5 mins.
①
Access to the LMT and check input power level.
②
Check cable connection status between a Donor An-
tennas.
③
Check the device output lower-limit level is set cor-
rectly.
④
If the input power is normal but the output power
reaches up to lower-limit, check the antenna isolation is
sufficient.
