Replacing The Led/Switch Board; Replacing The Telco Alarms Module (Tam) Board - Kontron CG2300 Installation And Maintenance Manual

5.2.15

Replacing the LED/Switch Board

The LED/switch board is mounted against the front panel of the CG2300 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 first 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. For instructions, see (A), (I), and (G) in Chapter 4.
Removing the Old LED/Switch Board
To remove the LED/Switch board:
1. 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 there is not enough room to access this screw, remove (or at least slide back) the FP board. For instructions, see
"Removing the Old Front Panel Board" in Section 5.2.14.
2. The LED/switch board is also attached to the front of the chassis by two standoffs. Once the retaining screw is
removed, pry the LED/switch board loose from these standoffs to remove it.
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 in order to attach it to the LED/switch board.
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" in Section 5.2.14.
5. Re-connect the multifunction cable on the FP board.
6. Re-install the fan cage, the baseboard power cables, the front bezel, and the chassis cover. For instructions, see (RC),
(RG), (RA), and (RL) in Chapter 6
7. If this is the last task you are performing inside the server chassis, plug in the power cord(s) and re-attach any
peripheral devices.
5.2.16

Replacing the Telco Alarms Module (TAM) Board

The TAM board is on the right side of the CG2300 server chassis floor, just below the front panel. Before you can replace the TAM
board, you must first remove the chassis cover, the support cross bar, the baseboard power cables, and the fan cage. (You do not
have to remove the front panel board in order to access the TAM board). For instructions, see (A), (D), (E1), and (G)
CAUTION: Before replacing any of the boards on the CG2300 server, first take the server out of service, turn off all peripheral
devices connected to the server, turn off the server by pressing the power button, and unplug the power cord(s) from the system
and wall outlet.
