Replacing the LED Status Panel
Step 1.
Replace the LED status panel in the server and screw in the two LED status panel mounting
screws.
Step 2.
Connect the LED status panel controller cable.
Step 3.
Replace the top metal cover and reconnect all power cables. Turn on the server and verify that the
server and power LEDs light up.
Step 4.
Copy a valid UUID to the new status panel.
NOTE
If resetting the UUID does not work successfully, contact your HP support
representative.
Step 5.
Verify the display panel replacement by exercising all front panel controls and observing that the
display panel LEDs are operating properly.
Removing and Replacing the System Board
CAUTION
Some server settings are saved to the LED status panel. If you are replacing both the LED
status panel and the system board, they must be replaced one at a time to avoid loss of server
settings. First replace one component, then turn on the server and boot to the EFI prompt.
After confirming that the first component has been replaced successfully, shut down the server
and replace the second component.
Removing the System Board
Step 1.
Turn off the server, disconnect all power and external cables and remove the top metal cover.
Step 2.
Remove these components from the system board:

Hardware” on page 87.
Step 4.
