3.6.9.2
Serial Ports
Both the SE7320SP2 and Server Board SE7525GP2 provide two serial ports: an external DB9
Serial port, and an internal DH-10 Serial header. The following sub-sections provide details on
the use of the serial ports.
Serial Port A
Serial A is an external 9-pin DB-9 connector that is located on the back edge of the
server board.
Serial Port B
Serial B is an optional port, accessed through a 9-pin internal DH-10 header. A standard
DH-10 to DB9 cable can be used to direct Serial A out the back of a given chassis. The
Serial B interface follows the standard RS232 pin-out as defined in the following table.

Floppy Disk Controller
The 34-pin floppy disk controller (FDC) in the SIO is functionally compatible with floppy disk
controllers in the DP8473 and N844077. All FDC functions are integrated into the SIO including
analog data separator and 16-byte FIFO.
3.6.9.4
Keyboard and Mouse
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” or connector insertion while the system is turned on.
3.6.9.5
Wake-up Control
The Super I/O contains functionality that allows various events to control the power-on and
power-off the system.
