DS3800HUMA1B1C Universal Memory Card Device Fault Diagnosis

The red indicator LED is on if an error has occurred. Before using the testing device, it is best practice to attempt to resolve the condition by using the reset switch. The reset switch stops processing and signal transmitting and receiving on the board without turning off power. If the error is caused by signals being out of sequence, the restart might resolve the issue. Because the board is powered on, only qualified technicians should use the reset button to restart the board. This to avoid shock and burns.

Quad A and Quad C also are populated with test points. If a problem occurs with the board, the components can be tested using a full-function testing device. The testing device must be in good working condition and calibrated to perform the testing. If a problem is pinpointed, the board might be a candidate for repair.
