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. 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.
