The HDD LED indicator would light when HDD works.

2.19.3Power LED (Pin 3 & Pin 4)

Pin 3 & Pin4

The Power LED indicator would light when the power is on.

2.19.4Suspend LED(Pin 5 & Pin 6)

Pin5&Pin6

The Suspend LED indicator would light when the computer is suspend.

2.19.5 Power Button (Pin 9 & Pin10)

The PCI-6886 provides an ATX power input connector. When connected with PIN 9 & PIN 10, it enables power On/Off from the chassis.

2.20 COM port connector (CN8,CN13,CN14)

The PCI-6886 provides four serial ports (COM1,COM3,COM4: RS-232

and COM2: RS232/RS422/RS485). CN13 supports COM1, CN14 sup- ports COM2, CN8 supports COM3, COM4. and JP1 is for COM2 RS232/ RS422/RS485 selection. It provides connections for serial devices (a mouse, etc.) or a communication network. You can find the pin assign- ments for the COM port connector in Appendix B.

2.21 MINI PS/2, KB/Mouse connector (CN19)

The PCI-6886 board provides a keyboard connector that supports both a keyboard and a PS/2 style mouse. In most cases, especially in embedded applications, a keyboard is not used. If the keyboard is not present, the standard PC/AT BIOS will report an error or fail during power-on self- test (POST) after a reset. The PCI-6886’s BIOS standard setup menu allows you to select "All, But Keyboard"under the "Halt On"selection. This allows no-keyboard operation in embedded system applications, without the system halting under POST.

2.22 External KB Connector(CN18)

In addition to the Mini keyboard connector on the PCI-6886’s rear plate, there is an additional onboard external keyboard connector, allowing for greater flexibility in system design.
