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).
