Power Switch

The power button switch (see Figure 6, A) can be used to turn the desktop board on or
off. This power button switch behaves the same as a chassis power switch connected
via the front panel header. The onboard power button switch does not remove
standby power. To turn off the computer using the onboard power button switch,
keep it pressed down for three seconds.

Reset Switch

The reset button switch (see Figure 6, B) can be used to reset the desktop board. This
power button switch behaves the same as a chassis reset switch connected via the
front panel header. When the reset button switch is pressed, the board resets and
runs the POST.
System Initialization/ Status LEDs
The Desktop Board provides LEDs that allow you to monitor your system's progress
through initialization and the BIOS POST (see Figure 7). There are also other board
status LEDs that allow you to monitor other system activities.
