Dealing
with
hardware
faults
Ensure
that
you
have
obtained
a
replacement
module
of
the
same
type
before
removing
any
faulty
module.
v
If
the
subsystem
power
is
turned
on
and
you
remove
any
module,
replace
it
immediately.
If
the
subsystem
is
used
with
modules
or
module
blanks
missing
for
more
than
a
few
minutes,
the
enclosure
can
overheat,
causing
power
failure
and
data
loss.
Such
use
will
invalidate
the
warranty.
v
Replace
a
faulty
drive
with
a
drive
of
the
same
type
and
equal
or
greater
capacity.
v
Refer
to
your
vendor-supplied
documentation
when
using
storage
software
for
handling
drive-related
hardware
faults.
v
All
drive
bays
must
be
installed
with
a
drive
carrier
module
in
order
to
maintain
a
balanced
airflow.
v
All
the
supplied
plug-in
power
supply
units,
electronics
modules
and
blank
modules
must
be
in
place
for
the
air
to
flow
correctly
around
the
cabinet.
CAUTION:
Observe
all
conventional
ESD
precautions
when
handling
modules
and
components.
Avoid
contact
with
backplane
components
and
module
connectors,
etc.
Note:
The
top
cover
of
the
enclosure
covers
a
service
area
which
should
be
accessed
only
by
qualified
service
personnel.
When
the
cover
is
replaced
it
must
be
secured
by
turning
the
lock
mechanism
to
the
locked
position.
Continuous
operation
during
replacement
Depending
on
how
the
enclosure
system
is
set
up,
if
a
disk
unit
fails,
it
can
normally
be
replaced
without
interrupting
the
use
of
the
system.
