The POWER LED indicates that the internal power supplies are operating.
When power is first applied, the unit will begin a countdown from 20 seconds. The
display will show the countdown from 20 seconds to 1 second, then the status of the
four OP's will be displayed. If the OP powers-up properly, its number will be
displayed. If the OP is in a fault condition, its OP number will be "00".
