Pump Control I/O PCB
The Pump Control I/O PCB, shown in Figure 6-5 , consists of two parts: the PCB itself and a
cover plate. In order to set the jumpers and switches on the I/O PCB, you must remove all the
connectors and the cover plate.
1 Remove the five green connectors from the front of the Pump Control I/O board. Remove the
board from the card cage in the same manner as the EXPMUX Pump Control CPU board.
2 Remove the four Phillips screws securing the cover plate to the PCB and remove the cover
plate.
