automatically switch back to the primary adapter when the primary adapter
comes back online. In this case, issue the command:
LOAD d :\ path \PCNTNW SCAN
where d and path are the drive and path where the driver is located. This
command causes the device driver to locate the primary adapter and switch
the Ethernet traffic to it.
Ethernet port connector
The following table shows the pin-number assignments for the RJ-45 connector. These
assignments apply to both 10BASE-T and 100BASE-TX devices.
Advanced System Management ports
Your server has three communication ports 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 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 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.
Cabling the server
The following illustration shows input/output connectors and cable routing for the
server.
