“Removing
the
ServeRAID
SAS
controller”
on
page
102)
Important:
Note
which
DIMMs
are
in
which
connectors,
before
you
remove
the
DIMMs.
You
must
install
them
in
the
same
configuration
on
the
replacement
system
board.
5.
Remove
all
DIMMs,
and
place
them
on
a
static-protective
surface
for
reinstallation
(see
“Removing
a
memory
module
(DIMM)”
on
page
114).
6.
Disconnect
all
cables
from
the
system
board.
7.
Slide
the
power
supplies
out
of
the
bays
slightly
or
remove
them
entirely
(see
“Removing
a
hot-swap
power
supply”
on
page
118).
8.
Slide
the
power
backplane
toward
the
right
side
of
the
server
(see
“Removing
the
power
backplane”
on
page
126).
Attention:
In
the
following
step,
do
not
allow
the
thermal
grease
to
come
in
contact
with
anything,
and
keep
each
heat
sink
paired
with
its
microprocessor
for
reinstallation.
Contact
with
any
surface
can
compromise
the
thermal
grease
and
the
microprocessor
socket;
a
mismatch
between
the
microprocessor
and
its
original
heat
sink
can
require
the
installation
of
a
new
heat
sink
instead.
9.
Remove
the
VRM
and
each
microprocessor
heat
sink
and
microprocessor;
then,
place
them
on
a
static-protective
surface
for
reinstallation
(see
“Removing
a
microprocessor”
on
page
134).
10.
Slide
the
shuttle
release
latch
toward
the
left
side
of
the
server,
and
push
the
shuttle
toward
the
rear
of
the
server
approximately
12.7
mm
(0.5
inch).
11.
Lift
the
shuttle
out
of
the
server.
12.
If
you
are
instructed
to
return
the
shuttle
assembly,
follow
all
packaging
instructions,
and
use
any
packaging
materials
for
shipping
that
are
supplied
to
you.
Installing
the
system
board
and
shuttle
Notes:
1.
When
you
reassemble
the
components
in
the
server,
be
sure
to
route
all
cables
carefully
so
that
they
are
not
exposed
to
excessive
pressure.
2.
When
you
replace
the
system
board,
you
must
either
update
the
server
with
the
latest
firmware
or
restore
the
pre-existing
firmware
that
the
customer
provides
on
a
diskette
or
CD
image.
To
reinstall
the
system
board
and
shuttle,
complete
the
following
steps.
