Replacing a power supply unit for a control enclosure

Remove and replace the power supply units in the control enclosure.
Replacing a Storwize V7000 Gen2 power supply unit for a control
enclosure
You can replace either of the two hot-swap redundant power supplies in an
enclosure. These redundant power supplies operate in parallel, one continuing to
power the enclosure if the other fails.
Before you begin
Attention:
v Even though many of these components are hot-swappable, they are intended to
be used only when your system is not active (no I/O operations). If your system
is powered on and processing I/O operations, go to the management GUI and
follow the fix procedures. Initiating the replacement actions without the
assistance of the fix procedures can result in loss of data or loss of access to
data.
v Be careful when you are replacing the hardware components that are located in
the back of the system that you do not inadvertently disturb or remove any
cables that you are not instructed to remove.
v Ensure that you are aware of the procedures for handling static-sensitive devices
before you replace the power supply.
