Removing and Replacing the Display Board
These procedures detail how to remove and replace the display board. The display board is
located behind the control panel and under the front cover. The display board contains the
server’s on/off switch and three LEDs that indicate server status.
WARNING! Ensure that the server is powered off and all power sources have been disconnected
from the server prior to removing or replacing the display board.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Failure to properly complete the steps in this procedure will result in erratic server
behavior or server failure. For assistance with this procedure, contact your local HP Authorized
Service Provider.
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety
precautions can result in damage to the server.
