Removing a Power Supply Module
If the system configuration includes three power supply modules, hot-
swapping is possible; allowing you to remove a power supply module
without powering down the system. If your configuration uses only two
modules, you must power down the system before removing or replacing
the failed power supply module.
1. Disconnect the AC power cables from the power supply modules. You
must hold the power supply retention clip to the side as you remove the
power cord (see Figure 27 on page 66).
2. Remove the four screws (Figure 27) holding the power supply module
to the back of the chassis.
3. Using the flared, vertical edges as handles and using both hands, slide
the power supply module straight back from its bay (Figure 27).

Caution!
You might feel initial
resistance in sliding the
power supply from its bay.
Do not tilt or twist the
supply. Resistance is
caused by the supply
disengaging from its 40-pin
connector. Use even, steady
force to remove the supply.
