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.
Table 3-4. Power Supply Redundancy Modes With a 10 Gb I/O Card

3 2+0 Non-redundant
