Redundant Power Supply Option
Systems with the optional redundant power supply feature contain a power-
supply paralleling board and a second 700-watt power supply module. In this
case, the two power supply modules each provide part of the power for the sys-
tem and are hot-pluggable (either power supply module can be removed and
replaced while the system is online and operational). Power distribution dia-
grams for both the redundant and nonredundant power configurations are
provided later in this chapter.
Pin Assignments for the DC Power Connectors
(Nonredundant Systems)
The power-supply output voltages for nonredundant systems can be measured
at the connectors on the back of the power supply (P1, P2, P3, P4, and P5) or at
Table 1-1. DC Voltage Ranges
