Replacing the control panel board
The control panel board is mounted on the front of the chassis, behind the
front bezel.

To replace the control panel board:

1Turn off the system and disconnect the power cord and all external
peripherals.
2Open the case. (See Opening the case on page 23 and Preventing static
electricity discharge on page 22.)
3Disconnect the front panel connector from the control panel board.
4Remove the screw that secures the board to the front of the chassis.
5Lift the control panel board off of the hooks on the front panel and
remove it.
6Install the new control panel board by placing the mounting slots of the
control panel board on the tabs on the front of the chassis, then slide
the board down until it locks into place. Be careful to keep the front panel
cable out of the way as you install the board.
7Replace the screw you removed in Step 4.
