Your server has one communication port dedicated to the Netfinity Advanced System
Management Processor. This port uses a standard D-shell serial-port connector,
labeled Management.
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.
If you install the Advanced System Management Interconnect cable option, it
provides two additional ports, which are used for the RS-485 function. These two
ports use a dual RJ-45 connector. The RS-485 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.
Note: When using the RS-485 function, at least one of the servers in the group that is
connected together must have an IBM Netfinity Advanced Systems
Management PCI Adapter installed.
