Removing and Replacing a Power Supply
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 supply, you must power off the library before performing this
procedure.
