6. If you suspect a hardware error, follow these steps:
a. Log users off the LAN and power down the HP Server.
b. Extend the HP Server out of the rack and remove the top cover.
c. Simplify the HP Server configuration to the minimum required:
∗ Monitor
∗ Keyboard
∗ Mouse
∗ 1 hard disk drive and 1 flexible disk drive
∗ 1 DVD
d. Remove all third-party options, and reinstall each one, one at a time, checking the HP
Server after each installation.
e. Replace the top cover and reconnect the power cord and other cables.
f. Boot the HP Server and if it does not function properly, refer to the following procedures.
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 cords are connected.
2. Check the HP Server's power supplies.
a. Check that at least three 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.
If the HP Server Powers On but then Shuts Down with a Fault Light
Use this checklist to check for the following problems when the HP Server powers on and then off:
1. Check that a conductive item has not been dropped or left inside the server chassis.
2. Check the connections on all boards.
3. Check the cables for bent pins.
