System
reliability
guidelines
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that
the
following
requirements
are
met:
v
The
CD
or
DVD
drive
bay
has
a
drive
or
a
filler
panel
and
electromagnetic
compatibility
(EMC)
shield
installed
in
it.
v
There
is
adequate
space
around
the
server
to
allow
the
server
cooling
system
to
work
properly.
Leave
approximately
50
mm
(2.0
in.)
of
open
space
around
the
left
and
right
sides
of
the
server.
Leave
approximately
166
mm
(6.54
in.)
of
open
space
around
the
rear
of
the
server.
Do
not
place
objects
in
front
of
the
fans
or
air
baffles.
For
proper
cooling
and
airflow,
replace
the
server
cover
before
you
turn
on
the
server.
Operating
the
server
for
extended
periods
of
time
with
the
server
cover
removed
might
damage
server
components.
v
You
have
followed
the
cabling
instructions
that
come
with
optional
adapters.
v
All
fans
are
operating
correctly.
v
You
do
not
operate
the
server
without
the
air
baffles
installed.
Operating
the
server
without
the
air
baffles
might
cause
the
microprocessors
or
other
components
to
overheat.
v
Microprocessor
socket
1
always
contains
a
microprocessor
and
heat
sink.
Important:
The
server
will
not
start
if
microprocessor
socket
1
is
empty.
v
Microprocessor
socket
2
always
contains
either
a
microprocessor
baffle
or
a
microprocessor
and
heat
sink.
v
No
dual
inline
memory
modules
(DIMMs)
are
installed
in
connectors
7
through
12
if
microprocessor
socket
2
(system-board
identifier
CPU2)
is
empty.
The
server
does
not
support
this
configuration.
v
Each
installed
adapter
is
of
the
same
type
(PCI
Express
or
Hyper
Transport)
as
the
riser-card
assembly
in
which
it
is
installed.
Operating
the
server
with
an
unsupported
adapter
in
a
connector
on
the
riser-card
assembly
might
cause
unpredictable
results.
For
a
list
of
supported
adapters
for
the
server,
see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
v
You
do
not
install
a
graphics
adapter.
Operating
the
server
with
an
unsupported
graphics
adapter
might
cause
unpredictable
results.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
the
server
and
other
electronic
devices.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
To
reduce
the
possibility
of
damage
from
electrostatic
discharge,
observe
the
following
precautions:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
The
use
of
a
grounding
system
is
recommended.
For
example,
wear
an
electrostatic-discharge
wrist
strap,
if
one
is
available.
v
Handle
the
device
carefully,
holding
it
by
its
edges
or
its
frame.
v
Do
not
touch
solder
joints,
pins,
or
exposed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
damage
it.
