Status Description
Alarm indicator. If the indicator is
steady red:
l The lightning protection circuit of
the PEM is faulty.
l There is no power input.
If the indicator blinks once every two
seconds (0.5 Hz), the FAN is working
properly.
If the indicator blinks once every two
seconds (0.5 Hz), the fan module or
PEM is faulty, or not all PEMs are
powered on.
From the time the MPU/SRU is
powered on until it is registered, the
indicator status changes from off, blink
once every 250 ms (4 Hz), off, steady
on, and then to blink once every two
seconds (0.5 Hz).
After the MPU/SRU is registered, the
MPU/SRU is working properly if the
indicator blinks at 0.5 Hz.
NOTE
Possible causes for an offline indicator are:
l The BootROM is damaged.
l The MPU cannot be powered on.
Possible causes for the indicator blinking
quickly include:
l The CF card is faulty.
l The other control chips on the
MPU/SRU are faulty, preventing the
MPU/SRU from initializing.
If the indicator is steady off, the
MPU/SRU is in the normal state. If the
indicator is steady red, an alarm is
generated.
From the time the SFU is powered on
until it is registered, the indicator status
changes from off, blink once every 250
ms (4 Hz), off, steady on, and then to
blink once every two seconds (0.5 Hz).
After the SFU is registered, the SFU is
working properly if the indicator blinks
at 0.5 Hz.
