Chapter 4 Working Inside Your System
Power System
The system may be configured with one, two, or three 360 watt power
supplies.
• One power supply.
• Two power supplies and a power share board.
• Two power supplies without a power share board.
• Three power supplies and a power share board.
If a single power supply fails in a system with a power share board, the
yellow power supply failure LED on the front panel starts flashing.
Generally, a failed power supply can be replaced while the system is
running.

1. Observe the warnings and cautions on page 3, “Safety Guidelines.”
2. Unplug the AC power cord from the power supply.
3. Remove the screws that attach the power supply to the chassis, and set
them aside.
4. Slide the defective power supply out the back of the chassis.
