Serial Connectors; Gigabit Ethernet Port - IBM xSeries 205 Type 8480 Hardware Maintenance Manual And Troubleshooting Manual

Use the Configuration/Setup Utility program to configure the parallel connector as
bidirectional. With this configuration, data can be read from and written to a device.
In bidirectional mode, the server supports the ECP and EPP modes.

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 37 for the
location of this connector.

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
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
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.
