ID Name Class Severity Unit
139 LPA over current 0x0103 Error MPI
Description This can happen if the LPA is overdriven or it could be a hardware fault.
NOC Actions
Consult systems engineer to have the unit readjusted regarding downlink g
ain.
If that is not solving the problem, dispatch field tech to have it replaced.
Field Actions
Readjust systems gain in DL. If that does not solve the problem then replace
r
emote unit.
ID Name Class Severity Unit
140 LPA overpower 0x0103 Error MPI
Description This can happen if the LPA is overdriven.
NOC Actions Consult systems engineer to have the unit readjusted regarding downlink gain.
Field Actions
Readjust systems gain in DL. If that does not solve the problem then replace
remote unit.
