2.2.2.4.1 
Hard Drive Activity LED Header 
Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is 
being read from or written to a hard drive. 
2.2.2.4.2 
Reset Switch Header 
Pins 5 and 7 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. 
2.2.2.4.3 
Power/Sleep LED Header 
Pins 2 and 4 can be connected to a single- or dual-color LED.  Table 25 shows the 
default states for a single-color LED. 
Table 25.  States for a One-Color Power LED 
LED State 
Description

Power off/hibernate (S5/S4) 
Blinking Sleeping 
(S3) 
Steady Green 
Running/Away (S0/S1) 
 
 
NOTE 
The LED states listed in Table 25 are default settings that can be modified through 
BIOS setup.  Systems built with a dual-color front panel power LED can also use 
alternate color state options. 
2.2.2.4.4 
Power Switch Header 
Pins 6 and 8 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 circuitry 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 
circuitry will recognize another on/off signal.
