Replacing the Button Board
The button board contains the circuitry for the system’s power button and LED
indicators (power, LAN1, LAN2, hard disk drive). To replace it, follow these
procedures.
1.
Remove the cabinet cover (see the previous section in this chapter).
2.
Remove the front bezel (see the previous section in this chapter).
3.
Remove the two screws securing the button board to the system chassis and unplug
the button board to pin-header cable from the connector on the motherboard to
detach the button board.
Reverse the above sequence when installing the new button board.
