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:
1 Turn off the system and disconnect the power cord and all external
peripherals.
2 Open the case. (See “Opening the case” on page 23 and “Preventing static
electricity discharge” on page 22.)
3 Disconnect the front panel connector from the control panel board.
4 Remove the screw that secures the board to the front of the chassis.
5 Lift the control panel board off of the hooks on the front panel and
remove it.
6 Install 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.
7 Replace the screw you removed in Step 4.
