Removing and Replacing the Fan / Display Board
The fan/display board is a combination board that provides and supports the following
functionalities:
• Fan power for the server fans
• Power switch and status LEDs
• DVD drive
• Front panel USB port
• Front panel VGA port
The fan/display board contains the power switch and the following status LEDs:
• Power LED
• System health LED
• Internal health LED
• External health LED
• Locator (UID) LED
WARNING! Ensure that the system is powered off and all power sources are disconnected from
the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an AC power source is connected.
These voltages are 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: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
NOTE: The fan/display board includes a USB connector that supports USB 2.0 (480 Mbps) and
a VGA connector.
The fan/display board is also the secondary location of the UUID for the server. Do not remove
the system board and fan/display board at the same time, or the UUID is deleted from the server.
The procedure for removing the fan/display board for the Data Center server is the same for the
Office friendly server.
