Pin Assignments for the DC Power Connectors (Redundant
Systems)
The power-supply output voltages for redundant systems can be measured at the
connectors on the power-supply paralleling board (PWR1, PWR2, PWR3,
PWRSCSI, and PWRFD) or at the connectors on the end of the wire bundles
extending from these connectors (PWR1, PWR2, PWR3, DDBP, and
FD1–FD4) (see Figures 1-12 through 1-15).
