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.
v
You
have
not
installed
any
small
computer
system
interface
(SCSI)
devices.
The
blade
server
does
not
support
SCSI
devices.
If
you
attach
SCSI
devices
to
the
blade
server,
these
devices
will
not
be
recognized
or
configured,
and
they
will
not
operate.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
the
blade
server,
the
BladeCenter
unit,
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
T
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
ESD
connector
on
the
front
or
back
of
the
BladeCenter
T
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
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
any
unpainted
metal
surface
of
the
BladeCenter
chassis
or
any
unpainted
metal
surface
on
any
other
grounded
rack
component
in
the
rack
in
which
you
are
installing
the
device
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
down
the
device.
If
it
is
necessary
to
set
down
the
device,
put
it
in
its
static-protective
package.
Do
not
place
the
device
on
your
BladeCenter
chassis
or
on
a
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather.
Heating
reduces
indoor
humidity
and
increases
static
electricity.
