If
the
problem
is
solved
when
you
remove
an
adapter
from
the
server
but
the
problem
recurs
when
you
reinstall
the
same
adapter,
suspect
the
adapter;
if
the
problem
recurs
when
you
replace
the
adapter
with
a
different
one,
suspect
the
PCI-X
board.
If
you
suspect
a
networking
problem
and
the
server
passes
all
the
system
tests,
suspect
a
network
cabling
problem
that
is
external
to
the
server.
