Considerations
Review the following considerations when installing the device.

The switch can be running while a power supply is being installed or removed, but the power supply being replaced must not be connected to a power source.
Note: Saving the switch configuration before replacing a power supply is recommended. - All slots must be filled or covered with a blank for operation (even though power supply or fans may not be functional).
-
