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: http://www.ibm.com/pc/us/netfinity/ 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 36 Netfinity Server HMM
