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.

RJ45	Signal	Abbreviation	DB9
1	Request to Send	RTS	7
2	Data Terminal Ready	DTR	4
3	Transmitted Data	TD	3
4	Signal Ground	SGND	5
5	Ring Indicator	RI	9
6	Received Data	RD	2
7	DCD or DSR	DCD/DSR	1 or 6 (see note)
8	Clear To Send	CTS	8

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.

3.5.1.2Floppy Disk Controller

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

3.5.1.3Keyboard 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.
