Hot-swap power supply unit replacement
Use this information to remove and install a hot-swap power supply unit.
Remove a hot-swap power supply unit
Follow instructions in this section to remove a power supply unit.
About this task
If the power supply unit to be removed is the only one installed, the power supply unit is non-hot-swap.
Before removing it, you must turn off the server first. To support redundancy mode or hot-swap, install an
additional hot-swap power supply unit.
Attention:
• Read
“Installation Guidelines” on page 45 and “Safety inspection checklist” on page 46 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.
