Netfinity 5000 - Configuring the Ethernet Controller
Applicable to: World-Wide
Configuring the Ethernet Controller
Your Netfinity 5000 comes with an Ethernet controller on the system board. The Ethernet controller provides 10BASE-T and 100BASE-TX support through the RJ-45 connector on the back of your server.
When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). This process is also known as auto-negotiation. This auto-negotiation occurs without software intervention. The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.
Auto-negotiation works only if the hub or switch to which your server is connected also supports auto-negotiation. If the hub or switch does not support auto-negotiation, the speed (10 Mbps or 100 Mbps) will still be detected correctly, but half-duplex mode will always be selected. A full-duplex switch that does not support auto-negotiation will not attach to the Netfinity 5000 in full-duplex mode.
In this case, if you want the network to operate in full-duplex mode, you must manually override the settings to obtain a full-duplex connection. To do this, your server must have a device driver that supports manual overrides. Use the ServerGuide CDs to install this device driver. Refer to the ServerGuide and Netfinity Manager Information section of this Server Library for instructions on installing device drivers. The ServerGuide CDs contain IBM Update Connector, a dial-up 1 program that keeps your BIOS and device drivers current. Verify that you have installed the appropriate device driver. Also, refer to your Ethernet documentation for additional information on operating modes, manual overrides, and device drivers.

Attention: The 10BASE-T Ethernet and the 100BASE-TX Fast Ethernet cabling in the network must be Category 5 or higher to meet various standards, including electromagnetic compatibility. You must install a device driver to enable your operating system to address the Ethernet controller. Use the ServerGuide CDs to install this device driver. Refer to the information in the ServerGuide and Netfinity Manager Information section of this Server 1 Response time will vary, depending on the number and nature of calls received. Library for instructions on installing device drivers, or for more information about the ServerGuide CDs. |
Fast Ethernet operates at a data rate of up to 100 Mbps. However, except for the different operating speeds, Fast Ethernet and standard Ethernet are structurally identical. Most applications and protocols that are currently installed on a standard Ethernet system can be seamlessly migrated to 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 most-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.

If you need additional Ethernet connections, you can install an Ethernet adapter, such as an IBM 10/100 Ethernet adapter. Review your network-adapter documentation for any additional configuration requirements.
