The PSERR LED performs this sequence even if the
CPU board is not installed.

This LED is normally OFF.
If illuminating green, check the following:
• Check the power supply voltages on the CPU PCB.
• Check for proper fan operation.

Illuminates green when the Battery Simulator is
instructed to turn ON, otherwise it is OFF.
• Illuminating green indicates only that the Battery
Simulator is instructed to turn ON, and is not an
indication of proper operation.
