Serial Port A 
Serial A is an optional port, accessed through a 9-pin internal header (J9A2). A standard DH-10 
to DB9 cable can be used to direct Serial A out the back of a given chassis. The Serial A 
interface follows the standard RS232 pin-out. The baseboard has a Serial Port A silkscreen 
label next to the connector as well as a location designator of J9A2. The Serial A connector is 
located next to the P64-C low-profile PCI card slot. A standard DH-10 to DB9 cable is available 
from Intel Corporation in the SE7501WV2 Serial Port Accessory Kit.

Serial Port B 
Serial B is an external low profile 8-pin RJ45 connector that is located on the back of the board. 
For those server applications that require an external modem, an RJ45-to-DB9 adapter is 
necessary. A standard DH-10 to DB9 cable is available from Intel in the SE7501WV2 Serial Port 
Accessory Kit.

Serial Port Multiplexer Logic 
The SE7501WV2 server board has a multiplexer to connect the rear RJ45 connector to either 
Serial Port A or Serial Port B in both the Intel® Server Chassis SR1300 and SR2300. This 
facilitates the routing of Serial Port A to the rear RJ45 connector if Serial Port B is used for SOL 
(Serial Over LAN) in both the SR1300 and SR2300 server chassis. This serial port selection can 
be done through the BIOS setup option. 
The following figure shows the serial port mux functionality.
