1 = Automatic
OFM=11 would force a mute of the block in slot one if slot one is
offline as indicated by the switch position(blinking yellow or red
LED). It would force an "un- mute" of the block in slot one if slot
one is online and not faulted as indicated by the switch
position(steady green LED).
OFM=20 would be existing behavior for the block in slot two.
OFM=21 would force a mute of the block in slot one if slot two is
offline as indicated by the switch position(blinking yellow or red
LED). It would force an "un- mute" of the block in slot two if slot
two is online and not faulted as indicated by the switch
position(steady green LED).
These settings would be kept in NVRAM and would come from
the factory as "OFM=10" and "OFM=20"

The offline unit has to be set for online, otherwise the OFM
command won't work properly.
