Reinstall,
turn

If
the
problem
is
solved
when
you
remove
the
device
from
the
blade
server
but
the
problem
recurs
when
you
reinstall
the
same
device,
suspect
the
device;
if
the
problem
recurs
when
you
replace
the
device
with
a
different
one,
suspect
the
system
board.
Have
a
trained
service
technician
replace
the
system
board
assembly.
If
you
suspect
a
networking
problem
and
the
blade
server
passes
all
the
system
tests,
suspect
the
network
switch.
Note:
The
problem
may
concern
the
network
and
be
external
to
