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 down 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 could 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 could result in damage to the server.
