Configuring the Ethernet Controller You must install a device driver to enable your operating system to address the Ethernet controller. Use ServerGuide to install this device driver. Refer to your ServerGuide package for instructions on installing device drivers. For more information about ServerGuide, see "What Your IBM Netfinity 3500 Server Offers" on page 4. Fast Ethernet operates at a data rate of 100 Mbps; that is, ten times faster than standard Ethernet. However, except for the different operating speeds, Fast Ethernet and standard Ethernet are structurally identical. Applications 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 your operating system before you use the Ethernet controller. The Ethernet controller supports the auto-detection mode only. When you install your device drivers and configure the Ethernet controller for use with your operating system, do not select the 10BASE-T mode. To ensure proper operation of your controller, always select the default parameters provided. Chapter 3. Configuring Your Server 45
