ODU PLL Lock Lost
Critical
Check if problem is
caused by faulty
DiSEqC
communication. If
not send ODU for
repair.
First check if there are errors on the
DiSEqC communication between the IDU
and ODU by using CLI command odu
show –diseqc. If DiSEqC errors are
reported the likely source of the problem
is a bad TX cable connecting the IDU to
the ODU, or poor connection of the cable
to the connectors. Please always ensure
that there is a good connection of the
shield of the cable (GND) to connectors in
both ends of the cable. If no errors are
reported on the DISEqC communication,
then the ODU is not able to transmit with
the correct TX frequency and must be sent
for repair.
ODU HPA failure
Critical
Check if problem is
caused by faulty
DiSEqC
communication. If
not send ODU for
repair.
The VSAT is not able to start the HPA of
the SatLink 4033 BUC.
ODU Short Circuit
Critical
Find and remove
cause of short-
circuit.
Restart VSAT.
The power supply to the BUC has been
short-circuited. After removing the cause
of short-circuit, the VSAT must be
restarted in order to recover.
ODU Diseqc
communication
Warning
Major
Check TX cable
connecting IDU to
ODU.
There are detected parity errors on more
than 4% of the DiSEqC messages. This
normally indicates a poor TX cable
connection from the IDU to the ODU.
ODU Diseqc
communication
Critical
Critical
Check TX cable
connecting IDU to
ODU.
There are detected parity errors on more
than 30% of the DiSEqC messages. This
normally indicates a poor TX cable
connection from the IDU to the ODU.
LNB Short Circuit
Critical
Find and remove
cause of short-
circuit.
Restart VSAT.
The power supply to the LNB has been
short-circuited. After removing the cause
of short-circuit, the VSAT must be
restarted to recover.
ODU TX calibration
completed
Normal
None
This event is logged after a successful
calibration of the transmitter. Required use
of the SatLink 4033 ODU.
ODU TX calibration
failed
Major
Check is problem is
caused by faulty
cabling of the ODU.
This event is logged after the calibration
of the transmitter failed. Required use of
the SatLink 4033 ODU.
Unit Temperature High
Major
Check temperature
at IDU location
Temperature inside the IDU is getting too
high.

Critical
Critical
Check temperature
at IDU location
Temperature inside the IDU has gotten too
high.
Failed to load
firmware
Critical
Send the IDU for
repair.
The IDU cannot access the satellite
interface because failing to load the
firmware. The IDU must be sent for
repair.
