Serial port

Your server has one standard serial port. Some application programs require specific ports, and some modems function properly only at certain communication port addresses. You might need to use the Configuration/Setup Utility program to change communication port address assignments to prevent or resolve address conflicts. This serial port is also manually configurable from inside of the server. The following table lists the function of each of the connectors which can be used to manually configure the serial port. You will also need to refer to the figure in “System board options connectors” on page 40.

Connectors	Port	Description
J52	Serial A / Systems	Default connection. Used by OS and Advanced System
	Management Port	Management Processor. Modem can be connected so
		that the system can dial out during problems.
J51	Serial Port B	Used by OS only.
J53	Management Port	Used by Advanced System Management Processor to
		utilize modem dial up functions.
