How to Remove a Power Supply

Before You Begin

Power supplies are hot-swappable. It is not necessary to power off the system if you
are removing a faulty power supply. For more information, see "About the Power
Supplies" in your Sun Fire V490 Server Administration Guide.
When both power supplies are functioning normally, both power supplies'
OK-to-Remove LEDs are lit. If a power supply fails, the system Fault LED and the
failed power supply's Fault LED will light. The other power supply's OK-to-Remove
LED will be unlit, assuming the other power supply is still functioning normally. For
more information, see
Caution – Do not remove a power supply from a running system unless the power
supply OK-to-Remove LED is lit.
