Turn
on
the
power
to
each
device,
based
on
the
power-on
sequence
in

To
turn
on
power
to
the
storage
subsystem,
turn
on
the
power-supply
switches
on
the

Use
the
storage-management
software
and
the
Fault
LEDs
to
check
the
overall
status
of
the
storage
subsystem
and
its
components.
All
LEDs
should
be
green
on
the
front
of
the
storage
subsystem.
If
they
are
not,
use
the
storage-management
software
to
diagnose
the
problem
(see
“Monitoring
status
through
software”
on
page
96).
Note:
The
green
Drive
active
LED
and
amber
Drive
fault
LED
below
the
drive
CRUs
might
flash
intermittently
as
the
drives
spin-up.
Wait
until
the
storage
subsystem
is
finished
powering
up
before
checking
the
LEDs
on
the
front
of
the
storage
subsystem.
For
more
information,
see
“Checking
the
LEDs”
on
page

Turning
off
the
storage
subsystem
Attention:
Except
in
an
emergency,
never
turn
off
the
power
if
any
storage
subsystem
Fault
LEDs
are
on.
Correct
the
fault
before
you
turn
off
the
power.
Use
the
storage-management
software
and
the
Fault
LEDs
to
check
the
overall
status
of
the
storage
subsystem
and
its
components.
All
LEDs
should
be
green
on
the
front
of
the
storage
subsystem.
If
they
are
not,
use
the
storage-management
software
to
diagnose
the
problem
(see
“Monitoring
status
through
software”
on
page
96).
This
ensures
that
the
storage
subsystem
will
power
up
correctly
later.
For
more
information,
see
“Troubleshooting”
on
page
145.
The
storage
subsystem
is
designed
to
run
continuously,
24
hours
a
day.
After
you
turn
on
the
storage
subsystem,
do
not
turn
it
off.
Turn
off
the
power
only
when:
v
Instructions
in
a
hardware
or
software
procedure
require
you
to
turn
off
the
power.
v
A
service
technician
tells
you
to
turn
off
the
power.
v
A
power
outage
or
emergency
situation
occurs
(see
“Performing
an
emergency
shutdown”
on
page
95).
Statement
5
CAUTION:
The
power
control
button
on
the
device
and
the
power
supply
do
not
turn
off
the
electrical
current
supplied
to
the
device.
The
device
also
might
have
more
than
one
power
cord.
To
remove
all
electrical
current
from
the
device,
ensure
that
all
power
