Power Supply
The power supply system consists of the power supply bay and either one or two power supply
modules. The optional second module provides a redundant, 1+1 system.
Replacing a Power Supply Module
CAUTION
If you do not have the second, redundant power supply module, you must
take the server out of service before replacing the single module. AC input
power can remain on.
To replace a power supply module:
1. Grip and squeeze the module handle (Figure 55) to depress the latch that is the right side of the
handle.
2. Rotate the handle down while pulling the module toward you. As you pull the module out,
support the module with your free hand.
3. Insert a new power supply module in the bay.
4. Grip the module handle, rotate it down, and push the module into the bay.
5. When the module is nearly all of the way in, the handle will rotate up. At this time, push firmly
on the front of the handle to lock the latch.
6. The power supply module is now functional and the power supply fault indicator should not
be lit.
