5.5 Replacing the LED/Switch Board
The LED/switch board is mounted against the front panel of the NSN2U 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 front
chassis cover and the front bezel. You may also have to remove the front panel board,
or at least loosen it and slide it back, in order to access the LED/switch board
retaining screw.
Removing the Old LED/Switch Board
To remove the LED/Switch board:
1. Remove the front chassis cover. For instructions, see “Removing the Front Cover” in
Section 3.2.
2. Remove the front bezel. For instructions, see “Removing the Front Bezel” in Section
3.2.
Disconnect the LED/switch board power and signal cable from the FP board. See
3. Figure 50 for the location of this connector.
4. From behind the front panel, unfasten the screw on the top right side of the
LED/switch board.
