Configuring
the
Gigabit
Ethernet
controller
The
Ethernet
controller
is
integrated
on
the
system
board.
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).
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
Setup
and
Installation
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.
For
information
about
configuring
your
Ethernet
controller,
see
the
Broadcom
NetXtreme
Gigabit
Ethernet
Software
CD
that
comes
with
your
server.
For
updated
information
about
configuring
your
Ethernet
controller,
go
to
the
IBM
Support
Web
site
at
http://www.ibm.com/pc/support
and
navigate
to
the
area
for
your
specific
server
type.
From
this
area
you
can
download
documentation,
the
most
current
device
drivers
for
your
server,
and
software
that
supports
advanced
networking
functions.
After
downloading,
run
the
downloaded
program
launch.exe
.
High-performance
Ethernet
modes
Your
Ethernet
controller
supports
optional
modes,
such
as
teaming,
priority
packets,
load
balancing,
fault
tolerance,
and
virtual
LANs,
which
provide
higher
performance,
security,
and
throughput
for
your
server.
These
modes
apply
to
the
integrated
Ethernet
controller
and
to
the
controllers
on
supported
Ethernet
adapters.
Ethernet
port
connector
The
following
illustration
shows
the
pin-number
assignments
for
the
RJ-45
connector.
These
assignments
apply
to
both
10BASE-T
and
100/1000BASE-TX
devices.
