Advanced System Management ports

Your server has three communication ports that are dedicated to the 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 ASM
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 your server to communicate with the integrated Advanced System
Management processor.
The ASM 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.
