LED inspection
Disconnect the TE connector assembly from CN603 and connect the circuit shown in Fig. 1 to the CN603.
Turn on the power switch and check the PROTECTION LED, TEMP LED and MUTE LED light in red color and the POWER
LED lights in green color.
Also check the fans rotate in high speed.
After inspection, disconnect the circuit shown in fig. 1 from the CN603 and connect the TE connector assembly to the CN603.
