auto-negotiation, the Ethernet controller will set the appropriate duplex state. 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 FDX. The controller supports HDX and FDX modes at both speeds. The Ethernet controller is integrated on the system board. You do not need to set any jumpers or configure the controller for your operating system before you use the Ethernet controller. However, you must install a device driver to enable your operating system to address the Ethernet controller. The device drivers are provided on the ServerGuide CDs. Failover for redundant Ethernet: The IBM 10/100 Ethernet adapter or the IBM 10/100 Etherjet™ PCI family of adapters are optional, redundant network interface card (NIC) adapters that you can install in your server. If you install this NIC adapter and connect it to the same logical segment as the primary Ethernet controller, you can configure the server to support a failover function. You can configure either the integrated Ethernet controller or the NIC adapter as the primary Ethernet controller. In failover mode, if the primary Ethernet controller detects a link failure, all Ethernet traffic that is associated with it is switched to the redundant (secondary) controller. This switching occurs without any user intervention. When the primary link is restored, the Ethernet traffic switches back to the primary Ethernet controller. High Performance Ethernet Modes: Your Ethernet controller supports optional modes, such as teaming, priority packets, and virtual LANs, which provide higher performance and throughput for your server. Teaming Mode: Your Ethernet controller provides options, called teaming options. These options increase throughput and fault tolerance when running with Windows NT 4.0 or NetWare 4.1x or later. v Adapter Fault Tolerance (AFT) provides automatic redundancy for your adapter. If the primary adapter fails, the secondary adapter takes over. Adapter fault tolerance supports from 2 to 4 adapters per team. v Adaptive Load Balancing (ALB) enables you to balance the transmission data flow among 2 to 4 adapters. ALB also includes the AFT option. You can use ALB with any 100BASE-TX switch. v Cisco Fast EtherChannel (FEC) creates a team of 2 to 4 adapters to increase transmission and reception throughput. FEC also includes the AFT option. You can only use FEC with a switch that has FEC capability. 78 Hardware Maintenance Manual: xSeries 200
