Figure 1-3 Motherboard Power Supply LEDs (2 of 2)
To troubleshoot:
1. Turn the front panel switch on and ensure that the +15 Standby is good.
2. For all models except the E8267C, the ON/OFF control line should be > 3.5 Vdc.
For the E8267C, the ON_OFF control line should be < 3.5 Vdc.
The Power Switch/Flat-Panel Interface Board in the front panel assembly controls this signal.
