If the HP Server Will Not Power On

Use these steps to check for power related problems:

1. On the control panel, verify the LCD screen's backlight is lit (green glow).

a. If it is lit, the HP Server is receiving AC power.

b. If it is not lit, ensure the HP Server's power cord is connected.

2. Check the HP Server's power supplies.

a. Check that at least two power supplies and both power cords are

plugged in to the chassis.

b. Each power supply has three LEDs and the top LED is the Power

(PWR) LED.

∗ The top PWR LED glows a steady green when the HP Server's DC

power has been switched on.

∗ The PWR LED will blink green, if the DC power is switched off,

but AC power is properly connected.

3. If the PWR LED on any power supply is not a steady green, reseat the

power supply.

4. You can release the lever and then reset it, or remove the power supply

from the HP Server.

5. If all power supply LEDs are still blinking green, the HP Server might be

in a sleep state.

Refer to your NOS's instructions concerning sleep states.

6. Check that the boards are properly seated.

7. Check that the Server Management Cable is properly connected to the

Power Distribution Board and the Legacy I/O Board.

8. Check that the DC-DC Converters are properly seated.

If the HP Server System Fans Come on but then Shutdown After 5 Seconds

Use these steps to check for system fan related problems:

1. Check for Memory Board DC-DC Converter failure:

a. DC-DC converters are installed in a valid configuration.

b. DC-DC converters are of the proper voltages.

2. Check the embedded regulator on the Processor Baseboard for failure.
