and protocols that are currently installed on a standard
Ethernet system can be seamlessly migrated to a Fast
Ethernet system. (In a very small number of cases, minor
tuning might be required to adjust the application to the
faster response time of a Fast Ethernet system.) Because
of the equivalence of the two types of Ethernet, mixed
Ethernet and Fast Ethernet systems also can be designed
and implemented.
The bandwidth required at each workstation connected to
a server is generally far less than the bandwidth required
at the server. This is because the server might have to
handle the bandwidth of multiple workstations at the same
time. A cost-effective solution to the bandwidth
requirements of this type of system is a mixed Ethernet
and Fast Ethernet network. This mixed network consists
of standard Ethernet connections at the workstations and
Fast Ethernet connections at the servers.
The Ethernet controller is a PCI device, and is therefore a
Plug and Play device. You do not have to set any jumpers
or configure the controller for the operating system before
you use the Ethernet controller.
The Ethernet controller supports the auto-detection mode
only. When you install the device drivers and configure
the Ethernet controller for use with the operating system,
do not select the 10BASE-T mode. To ensure proper
operation of the controller, always select the default
parameters provided.
Notes
The Ethernet controller supports the operating
systems that the server supports. To find out which
operating systems the server supports, go to the
following World Wide Web address:

If you need additional Ethernet connections, you can install
an Ethernet adapter, such as an IBM 10/100 Ethernet
adapter. Review the network adapter documentation for
any additional configuration requirements.
Note
If you are installing an IBM 10/100 Ethernet adapter,
be sure to run the Ethernet diagnostics and record the
server's Ethernet configuration information before you
install the adapter.
Ethernet cable specifications
The Ethernet controller on the system board provides
10BASE-T and 100BASE-TX support through the RJ-45
connector on the back of the server. When you connect
the server to the network, the Ethernet controller
