Removing and Replacing
a Power Supply 12
These instructions explain how to remove a power supply and replace it
with a new one. You may need to replace a power supply if there are
problems with one that is currently in use.
If the library has a redundant power supply, you can replace the power
supply without powering off the library. If the library has only one power
