14.10.2 LED Behavior of the DC BUC Power for L-Band Tx
There are two LEDs that indicate the state of the DC BUC power for L-band TX.
The active LED corresponds to the selected voltage.
Both LEDs have the same behavior.
LED State Time Behavior Description
48V
or 24V
Off This voltage is not applied on the L-Band Tx interface.
Steady This voltage is currently applied on the L-Band Tx interface.

1s An overload alarm is present on the DC power supply.
The circuit protection mechanism of the power supply is
triggered and disables the output power.
The protection mechanism monitors every 1s if the overload is
removed and re-enables the DC supply if this is the case.
The following situations can trigger the overload alarm:
• The connected load is too high;
• When a long cable is shorted at the outdoor equipment end.
5s A short circuit alarm is present on the DC supply.
The circuit protection mechanism of the power supply is
triggered and disables the output power.The protection
mechanism monitors every 5s if the short circuit is removed
and re-enables the DC supply.
The following situations trigger the alarm:
• The connected load is too high;
• When a long cable is shorted at the outdoor equipment end.
When a short circuit is present, due to a direct
connection between the L-band Tx interface
and the earthing, the LEDs on the back panel
are off.
