Power Supplies

Your system supports the following power supply modules:

•1100 W (high output power supply)

•750 W (energy smart power supply)

When a 10 Gb I/O card is installed, the system must have at least two power supplies connected to an A/C power supply. The system requires two power supplies to provide standby power to the system. With a 1 GbE I/O card, only one PSU is required to provide standby power to the system. Table 3-4 and Table 3-5 lists the power supply redundancy modes for a 10 Gb I/O card and a 1 GbE I/O card.
