5.1.2.1 Shorting Board

The Shorting board allows the removal of the diode board without taking down the system.
This permits periodic maintenance of the diodes without having to power down or remove the
unit from the shelf. The Shorting board has an LED which is off when the board is in normal
operational mode and is green when in the bypass mode of operation. With the Shorting
Board in the maintenance mode, the Diode Board can be removed for maintenance while still
allowing the FAP to operate. No OR'ed power is available in this mode. After installing the
Diode Board, the Shorting Board must be reset to normal mode.
