Active:
The LED Indicator is lit when the Common Module is active (driving the backplane signals).
Board OK:
The LED Indicator is lit when the Common Module determines that its on-board functions are
operating properly. The Indicator blinks during initial power-up boot delay, during which no
redundant-mode operation takes place.
Configured:
The LED Indicator is lit when the inactive Common Module receives its first complete
configuration set after power-up, or after becoming inactive due to a swap. An active module is
by definition configured and its indicator is always lit.
The Current state of a CM4 Common Module can also be determined over a network management link
(RS-232 or NCM[E1]).
