drives
are
locked
securely
in
place.
v
The
enclosure
IDs
on
the
storage
expansion
enclosure
are
set

2.
Check
the
system
documentation
for
all
the
hardware
devices
you
intend
to
turn
on
and
determine
the
proper
startup
sequence.
Note:

the
same
time
as
you
turn
on
the

3.
Turn
on
the
power
to
each
device,
based
on
the
startup
sequence.
Attention:
If
you
are
restarting
the
system
after
a
normal
shutdown,
wait
at
least
10
seconds
before
you
turn
on
the
power-supply
switches.
4.
Turn
on
both
power-supply
switches
on
the
back
of
the
unit.
The
storage
expansion
enclosure
might
take
a
few
seconds
to
turn
on.
During
this
time,
you
might
see
the
amber
and
green
LEDs
on
the
storage
expansion
enclosure
flash
intermittently.
When
the
startup
sequence
is

only
the
green
LEDs
on
the
front
and
back
are
lit.
If
other
amber
LEDs
remain
lit,
see
Note:
If
any
DS4000
EXP710
enclosures
are
present
in
the
drive
loop
and
the
DS4000
controller
firmware
is
not
at
version
6.10.xx.xx
or
higher,
the
Enclosure
ID
conflict
LED
on
the
DS4000
EXP710s
will
light
(even
if
the
Enclosure
ID
is
set
to
a
unique
value
among
the
storage
expansion
enclosures
and
the
DS4000
storage
server
in
the
same
drive
loop).
After
you
upgrade
the
controller
firmware
to
version
06.10.xx.xx,
the
Enclosure
ID
conflict
LED
will
become
unlit.
