5.3.2 Serial Ports
The baseboard provides two RS-232C serial ports (Serial A is at the rear panel of the system,
Serial B is either at a knockout at the rear panel or defaults to the front panel). Serial A is a
D-subminiature 9-pin connector. Serial B is an RJ45 8-pin connector on the front panel or it is a
D-subminiature 9-pin connector at the rear panel of the system. Each serial port can be enabled
separately with the configuration control provided on the baseboard.
Serial B port can be used either as an Emergency Management Port (EMP) or as a serial port.
As an Emergency Management Port, serial B port is used as a communication path by the
server management RS-232 connection to the Front Panel Controller. This provides a level of
emergency management through an external modem. The RS-232 connection can be
monitored by the Front Panel Controller when the system is in a powered down (standby) state.
