System
reliability
guidelines
To
help
ensure
proper
cooling
and
system
reliability,
observe
the
following
guidelines:
v
Make
sure
that
processor
socket
2
always
contains
either
a
microprocessor
heat
sink-filler
or
a
microprocessor
and
heat
sink.
If
the
blade
server
has
only
one
microprocessor,
it
must
be
installed
in
microprocessor
socket
1.
v
To
maintain
proper
system
cooling,
do
not
operate
the
BladeCenter
unit
without
a
blade
server,
expansion
unit,
or
blade
filler
installed
in
each
blade
bay.
See
the
documentation
for
your
BladeCenter
unit
for
additional
information.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
the
blade
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
When
working
on
the
BladeCenter
unit,
use
an
electrostatic
discharge
(ESD)
wrist
strap,
especially
when
you
will
be
handling
modules,
options,
and
blade
servers.
To
work
properly,
the
wrist
strap
must
have
a
good
contact
at
both
ends
(touching
your
skin
at
one
end
and
firmly
connected
to
the
front
or
back
of
the
BladeCenter
unit).
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
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.
v
While
the
device
is
still
in
the
static-protective
package,
touch
it
to
an
unpainted
metal
part
of
the
BladeCenter
unit
or
any
unpainted
metal
surface
on
any
other
grounded
rack
component
in
the
rack
you
are
installing
the
device
in
for
at
least
2
seconds.
This
drains
static
electricity
from
the
package
and
from
your
body.
v
Remove
the
device
from
the
package
and
install
it
directly
into
the
blade
server
without
setting
down
the
device.
If
it
is
necessary
to
set
down
the
device,
put
it
back
into
the
static-protective
package.
Do
not
place
the
device
on
the
blade
server
cover
or
on
a
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather.
Heating
reduces
indoor
humidity
and
increases
static
electricity.
Returning
a
device
or
component
If
you
are
instructed
to
return
a
device
or
component,
follow
all
packaging
instructions,
and
use
any
packaging
materials
for
shipping
that
are
supplied
to
you.
