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 STM SatLink 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 to recover.
ODU Diseqc
communication
Warning
Major Check TX cable
connecting IDU to
ODU.
There is 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 is 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 STM 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 STM SatLink 4033 ODU.
