5.1.3.1 Jumper Board

The Jumper board has two connectors and a connector plug. During normal operation, the
connector plug is seated on the first connector. For maintenance operation, the jumper board
has to be removed and the connector plug moved to the second connector. In the
maintenance position, the connector plug connects both A and B power feeds to the fuse
panels so one or both diode boards can be safely removed. The OP/MAINT LED is green
when the Jumper board is in normal operational mode and is red when in the maintenance
mode of operation.
5.1.3.1.1 Maintenance Mode
Use this procedure to place the jumper board into maintenance mode. Maintenance mode
allows the removal of one or both diode boards without taking down the system.
