CDM-625 Advanced Satellite Modem Revision 1
Front Panel Operation MN-0000036 (Ref MN/CDM625.IOM)
The menu indicates:
•
which of the two CSATs in currently online
•
Operating mode
•
Waveguide Switch status, both Tx and Rx: Ok or Ft (fault)
•
Redundancy Controller Box voltages: 5V and 12V values, to aid trouble-shooting
system problems.
The operating modes may be selected:
•
AUTO
mode – when the Online ODU faults, the switchover is done
automatically
to replace the faulty unit.
•
MANUAL
mode – if the Switch set-up is changed to
Manual
,
there will be no
automatic switchover in the event of a fault occuring.
NOTE:
If the ODU Redundancy system is in
AUTO
mode, a ‘forced switch-over’ can only
occur if the currently
OFFLINE
unit is fault-free.
