System
reliability
guidelines
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that:
v
The
ventilation
holes
on
the
blade
server
are
not
blocked.
v
Each
of
the
blade
bays
on
the
front
of
the
BladeCenter
unit
has
a
blade
server
or
filler
blade
installed.
Do
not
operate
the
BladeCenter
unit
for
more
than
1
minute
without
a
blade
server
or
filler
blade
installed
in
each
blade
bay.
v
You
have
followed
the
reliability
guidelines
in
the
documentation
that
comes
with
the
BladeCenter
unit.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
electronic
devices
and
your
system.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
To
reduce
the
possibility
of
electrostatic
discharge,
observe
the
following
precautions:
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
printed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
damage
it.
v
While
the
device
is
still
in
its
static-protective
package,
touch
it
to
an
unpainted
metal
part
of
the
BladeCenter
chassis
for
at
least
2
seconds.
This
drains
static
electricity
from
the
package
and
from
your
body.
v
Remove
the
device
from
its
package
and
install
it
directly
into
the
blade
server
or
BladeCenter
unit
without
setting
the
device
down.
If
it
is
necessary
to
set
down
the
device,
put
it
back
into
its
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.
v
Wear
an
electrostatic-discharge
wrist
strap,
if
one
is
available.
