One port uses a standard D-shell serial-port connector, connector C. The other two ports, which are used for the Advanced System Management Interconnect function, use a dual RJ-45 connector. You can attach a dedicated modem to the D-shell system-management connector on the rear of the server to communicate with the integrated Netfinity Advanced System Management Processor. The Advanced System Management Interconnect 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. Cabling the server Refer to the following illustration for the location of input and output connectors and for an example of proper cable routing. 74 Hardware Maintenance Manual: Netfinity 7100 - Type 8666

Advanced System Management ports
The 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 Advanced
System Management Interconnect function, use a dual RJ-45 connector.
You can attach a dedicated modem to the D-shell system-management connector
on the rear of the server to communicate with the integrated Netfinity Advanced
System Management Processor.
The Advanced System Management Interconnect 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.
Cabling the server
Refer to the following illustration for the location of input and output connectors
and for an example of proper cable routing.
