Two additional MAC addresses are assigned to the Integrated Baseboard Management
Controller (Integrated BMC) embedded in the Intel
®
6321ESB I/O Controller Hub. These MAC
addresses are used by the Integrated BMC’s embedded network stack to enable IPMI remote
management over LAN. Integrated BMC LAN Channel 1 is assigned the NIC1 MAC address + 2,
and Integrated BMC LAN Channel 2 is assigned the NIC1 MAC address + 3.
3.7 Super I/O
Legacy I/O support is provided by using a National Semiconductor* PC87427 super I/O device.
This chip contains all of the necessary circuitry to support the following functions:
GPIOs
Two serial ports
Keyboard and mouse support
Wake up control
System health support
3.7.1 Serial Ports
The server board provides two serial ports: an external RJ-45 serial port, and an internal DH-10
serial header.
Serial A is an optional port accessed through a 9-pin internal DH-10 header. A standard DH10
to DB9 cable can be used to direct the Serial A port to the rear of a chassis. The Serial A
interface follows the standard RS-232 pin-out as defined in the following table:
Table 16. Serial A Header Pin-out

1 DCD
2 DSR
3 RX
4 RTS
5 TX
6 CTS
7 DTR
8 RI
9 GND
The rear RJ-45 Serial B port is a fully functional serial port that can support any standard serial
device. Using an RJ-45 connector for a serial port allows direct support for serial port
concentrators, which typically use RJ-45 connectors and are widely used in the high-density
server market. For server applications that use a serial concentrator to access the system
management features of the server board, a standard 8-pin CAT-5 cable from the serial
concentrator is plugged directly into the rear RJ-45 serial port.
To allow support for either of two serial port configuration standards, a jumper block located
directly behind the rear RJ-45 serial port must be configured appropriately according to the
desired standard. For serial concentrators that require a DCD signal, the jumper block must be
configured with the serial port jumper over pins 1 and 2. For serial concentrators that require a
