Replacing the Power Supply Modules
5. While pushing the release latch of the defective power supply to the
left, gently pull the module toward you with the handle.
Note: As soon as the module can slide freely in its bay, there is no need to keep
holding the release latch.
6. Pull the power supply module completely out of its bay.
7. Position the new power supply so that its release latch is at the right of
the handle.
8. Slide the new power supply into the empty bay until it stops (the
module will not be flush with the edge of the bay).
9. While pushing the release latch to the left, gently push the module in
its bay until it clicks into place.
