Table 1-170 Indicators
If this indicator is on, you can remove the board.
Before the board is powered on and registers, this indicator status
changes in the following sequence: off > blinks quickly > steady
on > blinks quickly > steady on > blinks slowly (0.5 Hz).
After the board is powered on and registers, if this indicator blinks at
0.5 Hz, the system is working properly.
If this indicator is steady on, an alarm is generated.
If this indicator is off, no alarm is generated.
If this indicator is steady on, the board functions as the master one.
