is active, and if it is OFF, the ES block is in
standby mode. The Bus A and Bus B LEDs
show which bus each connector is associated
with, e.g. in single (joined) bus mode both
Bus A LEDs would be on, and in dual (split)
bus mode Bus A would be on for one
connector and Bus B would be on for the
other connector.
The ES Activity LED shows if the ES Block of
