2. Check the front panel power LED visible through the hole in the flap covering the power
button.
• If it is flashing amber, housekeeping voltages are available. 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.
The iLO MP is typically accessed through a terminal attached to the iLO MP LAN port on
the rear bulkhead using a Ctrl-B CR key sequence. 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. If the system does not turn the DC power on, or
if it does not remain on, check the SEL for errors as described below. Alternatively, you can
press the power button (located behind the front bezel flap) to attempt to enable the DC
voltages.
