To
remove
a
microprocessor
and
heat
sink,
complete
the
following
steps.
Note:
The
following
illustration
shows
how
to
remove
a
microprocessor
and
heat
sink
from
the
blade
server;
removing
a
microprocessor
and
heat
sink
from
the
MPE
unit
is
similar.

Bezel assembly
1.
Read
the
safety
information
that
begins
on
page
vii
and
“Installation
guidelines”
on
page
63.
2.
If
the
blade
server
is
installed
in
a
BladeCenter
unit,
remove
it
(see
“Removing
the
blade
server
from
a
BladeCenter
unit”
on
page
65).
3.
Remove
the
blade
server
cover
(see
“Removing
the
blade
server
cover”
on
page
68).
4.
If
you
are
removing
a
microprocessor
from
the
blade
server
and
an
MPE
unit
is
installed,
remove
the
MPE
unit
(see
“Removing
an
expansion
unit”
on
page
70).
5.
Identify
the
microprocessor
that
is
to
be
removed.
Note:
If
you
are
replacing
a
failed
microprocessor,
make
sure
that
you
have
selected
the
correct
microprocessor
for
replacement
(see
“Light
path
diagnostics”
on
page
38).
6.
If
you
are
removing
microprocessor
2
(the
microprocessor
that
is
closest
to
the
front
of
the
blade
server
or
MPE
unit),
remove
the
bezel
assembly
(see
“Removing
the
bezel
assembly”
on
page
72).
7.
Remove
the
heat
sink.
Attention:
Do
not
touch
the
thermal
material
on
the
bottom
of
the
heat
sink.
Touching
the
thermal
material
will
contaminate
it.
If
the
thermal
material
on
the
microprocessor
or
heat
sink
becomes
contaminated,
you
must
replace
the
heat
sink.
a.
Loosen
the
captive
screws
on
one
side
of
the
heat
sink
to
break
the
seal
with
the
microprocessor.
b.
Press
firmly
on
all
of
the
captive
screws
and
loosen
them
with

pull
the
heat
sink
from
the
processor.
