Figure 15. Serial Port Configuration Jumper Location

For server applications that require a DB9 serial connector, an 8-pin RJ45-to-DB9 adapter must be used.

The following table provides the pin-out required for the adapter to provide RS232 support. A standard

DH10-to-DB9 cable and 8-pin RJ45 to DB9 DCD and DSR adapters are available from Intel in the Serial

Port Accessory Kit, product code: AXXRJ45DB92.

Note:

The RJ45-to-DB9 adapter should match the configuration of the serial device used. One of two pin-

out configurations is used, depending on whether the serial device requires a DSR or DCD signal. The

final adapter configuration should also match the desired pin-out of the RJ45 connector, as it can also be

configured to support either DSR or DCD.

3.5.1.2

Floppy Disk Controller

The server board does not support a floppy disk controller (FDC) interface. However, the system BIOS

does recognize USB floppy devices.

3.5.1.3

Keyboard and Mouse Support

Dual stacked PS/2 ports, located on the back edge of the server board, are provided for keyboard and

mouse support. Either port can support a mouse or keyboard. Neither port supports hot plugging.
