Serial Port
The main board provides a rear panel RJ45 serial port.
The COM serial port can be used either as an EMP or as a normal serial port. See Table 34. As an
EMP, the COM port is used as a communication path by the server management RS-232
connection to the Sahalee. This provides a level of emergency management through an external
modem. The RS-232 connection can be monitored by the Sahalee when the system is in a powered
down (standby) state.
