Description
If the indicator is on, the SRU is powered on,
but the software is not running.
If the indicator blinks once every 2s (0.5 Hz),
the system is running properly.
If the indicator blinks once every 0.25s (4 Hz),
the system is starting.
If the indicator is steady red, the SRU is faulty.
If the indicator is steady orange, the SRU is
installed, and the board is powered on.
This indicator shows whether the SRU is the
master SRU or slave SRU.
If the indicator is on, the SRU is the master
SRU.
If the indicator is off, the SRU is the slave
SRU.
Press this button to reset the SRU.
NOTE
Resetting the SRU will cause the loss of service
packets. Confirm the operation before you press the
Reset button.
If the indicator is on, the device supports time
and clock synchronization, and the clock
board is installed on the SRU.
If the indicator is off, the device supports time
and clock synchronization, but the clock board
is not installed on the SRU.
