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.
