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 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. Failover for redundant Ethernet: The IBM 10/100 Ethernet adapter or the IBM 10/100 Etherjet™ PCI family of adapters are optional, redundant network interface card (NIC) adapters that you can install in your server. If you install this NIC adapter and connect it to the same logical 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 that is associated with it is switched to the redundant (secondary) controller. This switching occurs without any user intervention. When the primary link is restored, the Ethernet traffic switches back to the primary Ethernet controller. 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 your 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 2 to 4 adapters per team. v Adaptive Load Balancing (ALB) enables you to balance the transmission data flow among 2 to 4 adapters. ALB also includes the AFT option. You can use ALB with any 100BASE-TX switch. v Cisco Fast EtherChannel (FEC) creates a team of 2 to 4 adapters to increase transmission and reception throughput. FEC also includes the AFT option. You can only use FEC with a switch that has FEC capability. 78 Hardware Maintenance Manual: xSeries 200

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
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.
Failover
for
redundant
Ethernet:
The
IBM
10/100
Ethernet
adapter
or
the
IBM
10/100
Etherjet
PCI
family
of
adapters
are
optional,
redundant
network
interface
card
(NIC)
adapters
that
you
can
install
in
your
server.
If
you
install
this
NIC
adapter
and
connect
it
to
the
same
logical
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
that
is
associated
with
it
is
switched
to
the
redundant
(secondary)
controller.
This
switching
occurs
without
any
user
intervention.
When
the
primary
link
is
restored,
the
Ethernet
traffic
switches
back
to
the
primary
Ethernet
controller.
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
your
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
2
to
4
adapters
per
team.
v
Adaptive
Load
Balancing
(ALB)
enables
you
to
balance
the
transmission
data
flow
among
2
to
4
adapters.
ALB
also
includes
the
AFT
option.
You
can
use
ALB
with
any
100BASE-TX
switch.
v
Cisco
Fast
EtherChannel
(FEC)
creates
a
team
of
2
to
4
adapters
to
increase
transmission
and
reception
throughput.
FEC
also
includes
the
AFT
option.
You
can
only
use
FEC
with
a
switch
that
has
FEC
capability.
