Intel Desktop Board D201GLY Technical Product Specification
2.2.2.3.1
Hard Drive Activity LED Header [Orange]
Pins 1 and 3 [Orange] can be connected to an LED to provide a visual indicator that
data is being read from or written to a hard drive. Proper LED function requires an
IDE hard drive connected to an onboard IDE connector.
2.2.2.3.2
Reset Switch Header [Blue]
Pins 5 and 7 [Blue] can be connected to a momentary single pole, single throw (SPST)
type switch that is normally open. When the switch is closed, the board resets and
runs the POST.
2.2.2.3.3
Power/Sleep LED Header [Green]
Pins 2 and 4 [Green] can be connected to a one- or two-color LED. Table 17 shows
the possible states for a one-color LED. Table 18 shows the possible states for a two-
color LED.

2.2.2.3.4
Power Switch Header [Red]
Pins 6 and 8 [Red] can be connected to a front panel momentary-contact power
switch. The switch must pull the SW_ON# pin to ground for at least 50 ms to signal
the power supply to switch on or off. (The time requirement is due to internal
debounce circuitry on the board.) At least two seconds must pass before the power
supply will recognize another on/off signal.
