Ethernet connector

The server comes with an integrated Ethernet controller. This controller provides
an interface for connecting to 10-MBps or 100-MBps networks and provides
full-duplex capability, which enables simultaneous transmission and reception of
data on the Ethernet LAN.
To access the Ethernet connector, connect a Category 3, 4, or 5 unshielded
twisted-pair (UTP) cable to the Ethernet (RJ-45) connector on the rear of the server.
See "I/O connector locations" on page 64.
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5.

Configuring the Ethernet controller

When you connect the server to the network, the Ethernet controller automatically
detects the data-transfer rate (10 MBps or 100 MBps) on the network and then sets
the controller to operate at the appropriate rate. In addition, if the Ethernet
connector that the server is connected to supports 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 full duplex (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.

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
the 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 two to four adapters per team.
v Adaptive Load Balancing (ALB) enables you to balance the transmission data
flow among two to four adapters. ALB also includes the AFT option. You can
use ALB with any 100BASE-TX switch.
