Ant Power Down
Failed
BDU is not able to power
down the antenna. Is
probably caused by a
defective transistor (FET)
on the power supply
PCB.
Replace the BDU
Power Supply boards.
Ant Power Up Failed
BDU is not able to power
up the antenna. Might
be caused by a short
circuit in the connecting
devices.
Antenna (ACU)
Wrong Type Check
Conf.
A wrong antenna type is
attached to the BDU
(e.g. a F55 antenna to a
F77 BDU).
Check/change Antenna
Control Unit.
Change Config Module
to correct type.
Antenna (FEU)
Wrong Type Check
Conf.
A wrong antenna type is
attached to the BDU
(e.g. a F55 antenna to a
F77 BDU).
Check/change High
Power Amplifier.
Change Config Module
to correct type.
FEU Status power
alarm
Checks the HPA output
power versus the
reference power is not
above threshold. If this
happens the antenna is
reset.
If persisting replace
the HPA.
FEU Status reset
HPA has been reset for
an unknown reason.
If alarm is persistent
the HPA is defect and
has to be replaced.
