Go to step 3. • If it is not illuminated or flashing, housekeeping voltages are not available. Check the LEDs on the power supplies. The power supplies have three LED indicators: - Predict Fail amber LED to the left - Failed amber LED in the center (a triangle with an exclamation point) - Green Power LED to the right If the Failed LED is illuminated, you must replace the power supply. If the green Power LED is illuminated or flashing, the supply is OK and has AC voltage applied. 3. Verify whether the iLO MP is functional.

If the iLO MP is functional, check the status of the DC power system using the CM> PC command or the CM> PS command. If the PC or PS command output shows the current system power state to be off, try to turn the DC power on using the PC command.

Alternatively, you can press the power button (located behind the front bezel flap) to attempt to enable the DC voltages. Troubleshooting System Power 131
