4.4.2 Replacing the SMU06C Main Control Board

Prerequisites



You have obtained an ESD wrist strap, a pair of ESD gloves, an ESD box or bag, the
cabinet door key, and tools.



The new main control board is intact.

Context



The SMU is not hot-swappable. You do not need to disconnect the AC input to the power
system.



Do not pull the LCD flat cable with excessive force.

Procedure

Step 1

Connect the ground cable for the ESD wrist strap, and put on the ESD wrist strap and ESD
gloves.

Step 2

Record SMU06C parameters.

Step 3

Flip the battery switch to MANUAL.

Step 4

Record the position of the signal cable connected to the SMU06C, and disconnect the signal
cable.

Step 5

Unscrew and remove the SMU06C, as shown in

Figure 4-3

Figure 4-3

Removing the SMU06C

Step 6

Disconnect cables from the input ports on the SMU06C main control board.

Step 7

Disconnect the LCD flat cable, as shown in

Figure 4-4

Hold the two sides of the locking latch on the LCD flat cable connector and gently and
levelly remove the locking latch.

Hold the LCD flat cable on its two sides and gently disconnect it from the connector.
