Pin Signal 4 Ground Table 20. USB-port connector pin-number assignments Ethernet port The server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10Mbps or 100-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). To access the Ethernet port, connect a Category 3, 4 or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of the server. Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the network be Category 5 or higher. The Ethernet (RJ-45) connector has two lights. The Ethernet link-status light is on the left. When this green light is on, there is an active connection on the Ethernet port. The Ethernet transmit/receive activity light on the right. When this amber light is on, there is activity between the server and the network. These lights have the same functions as the Ethernet link-status light and the Ethernet transmit/receive activity light on the information panel (see "Information LED panel" on page 10). Configuring the Ethernet controller When you connect the server to the network, the Ethernet controller automatically detects the data-transfer rate (10Mbps or 100Mbps) 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). The controller supports half-duplex (HDX) and fullduplex (FDX) modes at both speeds. The Ethernet controller is a PCI Plug and Play device. 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 Netfinity 10/100 Fault Tolerant Adapter is an optional redundant network interface card (NIC adapter) that you can install in the server. If you install this NIC adapter and connect it to the same logical LAN 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 associated with it is switched to the redundant (secondary) controller. If the appropriate device drivers are installed, this switching occurs without any user intervention. When the primary link is restored to an operational state, the Ether- Installing options 101
