What to Do
Caution – If a power supply fails and you do not have a replacement available,
leave the failed power supply installed to ensure proper system cooling.
1. Unlock and open the system doors.
2. Identify the power supply to be removed.
Check the power supply LEDs to determine which power supply is faulty. Before
continuing, make sure that the blue OK-to-Remove LED is lit on the power supply
you want to remove. For more information, see "Power Supply LEDs" on page 11
and the Sun Fire V440 Server Administration Guide.
