Power/Sleep LED Pins
Pins 2 and 4 can be connected to a one- or two-color LED. Table 22 shows the
possible states for a one-color power LED.
Table 22. States for a One-Color Power LED
LED State
Off
Blinking
Steady Green
NOTE
The LED states listed in Table 22 are default settings and can be modified through the
BIOS setup. Systems built with a dual-color front panel power LED can also use
alternate color state options.
Power Switch Pins
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 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.
Front Panel USB Headers
Figure 13 is a connection diagram for the standard front panel USB header (see
Figure 11, T).
