Serial connectors Your server has two standard 9-pin D-shell serial connectors: Serial connector 1 and Serial connector 2. See "System board external connectors" on page 36 for the location of this connector. 1 5 6 9 Gigabit Ethernet port Your server comes with an integrated Gigabit Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). Activity LED (green) Link LED (green) 8 1 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 your server. Note: The 100BASE-TX/1000BASE-T Fast Ethernet standard requires that the cabling in the network be Category 5 or higher. The Ethernet (RJ-45) connector has two LEDs. The Ethernet-link status LED is on the left. When this green light is on, there is an active connection on the Ethernet port. The Ethernet transmit/receive activity LED is on the right. When this amber LED is on, there is activity between the server and the network. These LEDs have the same functions as the Ethernet-link status LED and the Ethernet transmit/receive activity LED on the rear of the server (see the User's Guide). Configuring the Gigabit Ethernet controller 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 Device Drivers and IBM Enhanced Diagnostics CD. When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps, 100 Mbps, or 1000 Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet ports that your server is connected to support auto-negotiation, the Gigabit 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/1000BASE-T), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds. High-performance Ethernet modes Your Ethernet controller supports optional modes, such as teaming, load balancing, fault tolerance, and virtual LANs, which provide higher performance, security, and Chapter 4.
