The UUT power supplies attach to the power busses PB1-PB4.
Figure 4-4 shows the power bus connectors J801 and J802
located on the Switch/Load Unit backplane PC board for system
integrated SLU. These connectors use screw terminations for
high current capability. The J801 connectors are bussed
together on the PC board providing a common connection for up
to three supplies.

The following examples A and B show the two most common
ways of configuring the power busses.
Example A shows three separate supplies attached to the
busses, with all three sharing a common ground on Power Bus 1
(PB1). This is the factory default configuration. The grounds for
all three supplies are connected together on connector J801.
