Hot-swap power supply removal
The server comes with one power supply. You can add a
second power supply to provide redundant power. Each
power supply has two status indicators; see “Power
supplies” on page 224 for information about the status
indicators.
Attention
You cannot hot-swap a power supply if the server has
only one power supply installed.
Refer to the illustration in “Hot-swap power supply
installation” on page 181 while you perform the steps in
this procedure.
