You should see and hear several things happen:
■
The fans in the power supplies begin turning.
■
The top front panel LED (green) turns on immediately denoting the power
supply is delivering DC power.
■
The middle front panel LED (yellow) flashes while POST runs for
approximately 60 seconds. After 60 seconds, this LED turns off if the tests pass.
If the LED remains lighted after 60 seconds, a test has failed.
■
The bottom front panel LED (green) flashes to show that booting is successful
and the operating system is running. If this LED fails to turn on and the
middle LED is on, a severe hardware fault exists.
