Remove a power supply unit
Use this information to remove a power supply unit.
About this task
The following describes the information that you must consider when removing a power supply:
Note: If the power supply unit to be removed is the only one installed, the power supply is non-hot-swap 
and before removing it, you must turn off the server first. To support redundancy mode or hot-swap, install 
an additional hot-swap power supply.
Attention: 
•  Read “Installation Guidelines” on page 185 to ensure that you work safely.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.
