Identifying Problems through Status Indicators

Status indicators on the server can help to identify problems with some system components such as power supplies and hot-swap drives.

Power Supply Status Indicators

To recognize the state of the power supply, you must examine the following indicators:

ŸGreen Power-on LED on the front of the server

ŸAmber Power-fail LED on the front of the server

ŸPower Supply OK LED on the back of the power supply

ŸCurrent OK LED on the back of the power supply

When the server is lightly loaded, that is, when some of the adapter slots and drive bays are not filled, the power supply might continue to function properly, even when the status indicators show a problem.
