Advanced System Management ports

Your server has three communication ports dedicated to
the Netfinity Advanced System Management Processor.
One port uses a standard D-shell serial-port connector,
connector C. The other two ports, which are used for the
RS-485 function, use a dual RJ-45 connector.
You can attach a dedicated modem to the D-shell
system-management connector on the rear of your server
to communicate with the integrated Netfinity Advanced
System Management Processor.
The RS-485 function uses the RJ-45 system-management
connectors. This function enables you to connect the
Advanced System Management Processors of several
rack-mounted servers so that they can communicate with
each other in half-duplex mode.
