2.
   
An
 
amber
 
LED
 
is
 
lit
 
on
 
one
 
or
 
more
 
PSUs.
 
If
 
the
 
internal
 
temperature
 
measured
 
in
 
the
 
airflow
 
through
 
the
 
enclosure
 
exceeds
 
a
 
pre-set
 
threshold,
 
a
 
thermal
 
alarm
 
sound.
 
1.
   
Check
 
to
 
ensure
 
that
 
local
 
ambient
 
environment
 
temperature
 
is
 
below
 
the
 
upper
 
35°C
 
(95°F)
 
specification.
 
2.
   
Check
 
the
 
installation
 
for
 
any
 
airflow
 
restrictions
 
at
 
either
 
the
 
front
 
or
 
rear
 
of
 
the
 
enclosure.
 
A
 
minimum
 
gap
 
of
 
2.5
 
cm
 
(1

at
 
the
 
front
 
and
 
5

(2
 
inches)
 
mm
 
at
 
the
 
rear
 
is
 
recommended.
 
3.
   
Check
 
for
 
restrictions
 
due
 
to
 
dust
 
build
 
up;
 
clean
 
as
 
appropriate.
 
4.
   
Check
 
for
 
excessive
 
re-circulation
 
of
 
heated
 
air
 
from
 
rear
 
to
 
front.
 
Use
 
in
 
a

not
 
recommended.
 
5.
   
If
 
possible,
 
turn
 
off
 
the

and
 
investigate
 
the
 
problem
 
before
 
continuing.
  
Drive
 
carrier

faults
 
Each
 
Drive
 
Carrier
 
module
 
has
 
two
 
LEDs:
 
an
 
upper
 
(green)
 
LED
 
and
 
a
 
lower
 
(amber)
 
LED.
 
v
   
Under
 
normal
 
operation,
 
the
 
green
 
LED
 
is
 
on
 
and
 
will
 
flicker
 
as
 
the
 
drive
 
operates
 
v
   
Under
 
normal
 
operation,
 
the
 
amber
 
LED
 
will
 
be:
 
–
   
Off
 
if
 
there
 
is
 
no
 
drive
 
present
 
–
   
Off
 
as
 
the
 
drive
 
operates
 
–
   
On
 
if
 
a
 
drive

is
 
present
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
 
is
 
powered
 
up
 
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

to
 
flow
 
correctly
 
around
