3.4. Reconnect the TAM signal cable.
3.5. Reconnect the FP USB cable that comes from the baseboard.
3.6. Reconnect the LED HDD cable that comes from the SAS HDD backplane.
4. Re-install the eUSB module if used.
5. Replace the SD flash card in the SD module slot, if one was saved from the old FP board.
6. Replace the eUSB module if one was removed and saved from the old FP board.
7. If this is the last task you are performing inside the chassis, replace the front bezel and top chassis
cover and reconnect the power cord(s).
5.4 Replacing the LED/Switch Board
The LED/switch board is mounted against the front panel of the CG1200 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 and the front bezel. You may also
have to loosen the front panel board and slide it back, in order to access the LED/switch board retaining
screw.
5.4.1 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 Section 3.2.1, “Removing the Cover”.
3. Remove the front bezel. For instructions, see Section 3.2.3, “Removing the Front Bezel”.
4. From behind the front panel, disconnect the LED/switch board power and signal ribbon cable from the
LED/switch board (Figure 54, “A” and “B”).
5. Remove the optional eUSB module on the FP board if it is installed so there is enough room to
unfasten the retainer screw on the top right side of the LED/switch board (“C”).
If you still do not have enough room to access this screw, remove (or at least slide back) the FP
board. For instructions, see Section 5.3.1, “ Removing the Old Front Panel Board”.
6. 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 slide the LED/switch board to the left and away from these standoffs
to remove it (“D”).
