If
the
problem
remains,
suspect
the
following
FRUs
in
the
order
listed:
v
DIMM
v
System
board
v
Microprocessor
Notes:
1.
If
the
problem
is
solved
when
you
remove
an
I/O
adapter
from
the
blade
server
and
replacing

2.
If
you
suspect
a
networking
problem

system
tests,
suspect
a
network
cabling
problem
external
to
the
blade
server.
