sharing circuit that receives power from all three I/O power
supply modules.
Should any I/O power supply module fail, only one leg of the
transceiver modules will lose power: the two remaining legs

the I/O modules will continue to operate properly by drawing
their current from the two remaining power supplies within
the I/O power supply assembly.
