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 computer to the network, the Ethernet controller
automatically detects the data-transfer rate (10 Mbps, 100 Mbps, or 1 Gbps) on
the network and then sets the controller to operate at the appropriate rate. In
addition, if the Ethernet ports that your computer is connected to support
auto-negotiation, the Gigabit Ethernet controller sets the appropriate duplex state.
That is, the Ethernet controller adjusts 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
throughput for your computer. These modes apply to the integrated Ethernet
controller and to the controllers on supported Ethernet adapters.
SCSI cabling requirements
If your computer comes with a SCSI adapter, you can install three internal SCSI
devices using the SCSI signal cable that comes with it. If you plan to attach
external SCSI devices, you must order an additional SCSI cable. To select and
order the correct cables for use with external devices, contact your IBM reseller or
IBM marketing representative. To receive an indication of SCSI hard disk drive
activity, you must also connect the SCSI adapter to the SCSI LED (J35) connector
on the system board (see "System board" on page 58 for the location of the internal
SCSI connector).
Setting SCSI IDs
Each SCSI device connected to a SCSI controller must have a unique SCSI ID.
This ID enables the SCSI controller to identify the device and ensure that different
devices on the same SCSI channel do not attempt to transfer data simultaneously.
SCSI devices that are connected to different SCSI channels can have duplicate
SCSI IDs. See the information that is provided with the device for instructions for
setting its SCSI ID. With a SCSI adapter installed in your computer, you can use its
68-pin SCSI connector to connect different types of SCSI devices.
To install SCSI devices, you must have an optional PCI SCSI adapter installed. See
the information that is provided with the device for instructions to set its SCSI ID.
