Kontron CG2200 Carrier Grade Server Installation and Maintenance Guide
8. If this is the last task you are performing inside the chassis, replace the top chassis cover and
reconnect the power cord(s).
5.5 Replacing the LED/Switch Board
The LED/switch board is mounted against the front panel of the CG2200 server chassis because it
supports the LEDs and switches that are on the control panel on the front of the chassis. Before you can
replace the LED/switch board, you must remove the chassis cover, the front bezel, and the fan cage so
you can access the board from the back. You may also have to loosen the front panel board and slide it
back, in order to access the LED/switch board retaining screw.
5.5.1 Removing the Old LED/Switch Board
To remove the LED/Switch board:
1. Power down the server and remove all peripheral devices and the power cord(s)
2. Remove the chassis cover. For instructions, see “Removing the Cover”.
3. Remove the front bezel. For instructions, see “Removing the Front Bezel”.
4. Remove the sheet metal fan cage. For instructions, see “Removing the Fan Cage”.
5. From behind the front panel, disconnect the LED/switch board power and signal ribbon cable from the
LED/switch board.
6. Disconnect the multifunction cable on the FP board so there is enough room to unfasten the retainer
screw on the top right side of the LED/switch board.
If you still do not have enough room to access this screw, remove (or at least slide back) the FP
board. For instructions, see “Removing the Old Front Panel Board”.
7. The LED/switch board is also attached to the front of the chassis by two standoffs. Once the retaining
screw is removed, you need to pry the LED/switch board loose from these standoffs to remove it.
5.5.2 Replacing the LED/Switch Light Pipe Assembly
1. Remove the black control panel module from the front of the chassis by lifting up from the bottom and
then pulling down to release the top tabs holding it into the chassis frame.
2. Position the new control panel module with the top tabs in the appropriate slots. Gently push down
and in to secure the bottom of the panel to attach it to the LED/switch board.
5.5.3 Installing the New LED/Switch Board
1. Connect the LED/switch board power and signal ribbon cable to the new LED/switch board.
2. Align the left side of the LED/switch board with the two standoffs on the inside of the front panel of the
chassis and gently push the board to secure it to the chassis frame.
3. Fasten the screw at the right of the LED/switch board to hold the board in place.
4. Replace the front panel board if you removed it or slid it out to work on the LED/switch board
installation. For instructions, see “Installing the New Front Panel Board”.
5. Reconnect the multifunction cable on the FP board.
6. Replace the fan cage.
7. Replace the front bezel. For instructions, see “Re-Installing the Front Bezel”.
8. If this is the last task you are performing inside the server chassis, replace the chassis cover,
reconnect the power cord(s), and reconnect any external devices.
