Description
FRU/action
The

not
work.
v
Make
sure
that
the
hub/switch
is
turned
on.
v
Check
all
connections
at
the
Ethernet
controller
and
the
hub/switch.
v
Use
another
port
on
the
hub/switch.
v
If
the
hub/switch
does
not
support
auto-negotiation,
manually
configure
the
Ethernet
controller
to
match
the
hub/switch.
v
If
you
manually
configured
the
Duplex
mode,
make
sure
that
you
also
manually
configure
the
speed.
The
Ethernet
transmit/receive
activity
LED
does
not
work.
v
Make
sure
that
you
have
installed
the
network
device
drivers.
v
The
network
might
be
idle.
Try
sending
data
from
this
server.
Data
is
incorrect
or
sporadic.
v
Make
sure
that
you
are
using
Category
5
or
higher
cabling
when
operating
the
server
at
100
Mbps
or
at
1000
Mbps.
v
Make
sure
that
the
cables
do
not
run
close
to
noise-inducing
sources
like
fluorescent
lights.
The
Ethernet
controller
stopped
working
when
another
adapter
was
added
to
the
server.
v
Make
sure
that
the
cable
is
connected
to
the
Ethernet
controller.
v
Make
sure
that
the
PCI
system
BIOS
code
is
current.
v
Reseat
the
adapter.
v
Determine
whether
the
interrupt
(IRQ)
setting
that
is
assigned
to
the
Ethernet
adapter
is
also
assigned
to
another
device
in
the
system.
Use
the
Configuration/Setup
Utility
program
to
determine
whether
this
is
the
case.
Although
interrupt
sharing
is
allowed
for
PCI
devices,
some
devices
do
not
function
well
when
they
share
an
interrupt
with
a
dissimilar
PCI
device.
Try
changing
the
IRQ
that
is
assigned
to
the
Ethernet
adapter
or
the
other
device.
v
Reseat
or
replace
the
adapter.
The
Ethernet
controller
stopped
working
without
apparent
cause.
v
Try
a
different
port
on
the
hub/switch.
v
Reinstall
the
device
drivers.
See
the
operating-system
documentation
and
the
ServerGuide
information.
