Return
enclosure
to
fully
home
position
and
attach
to
rack
using
captive
fasteners
on
front
flanges.
Note:
Rack
rails
have
features
to
restrict
complete
enclosure
withdrawal
while
still
allowing
access
to
the
cooling
fans.
If
it
becomes
necessary
to
completely
remove
the
system,
pull
the

out
until
it
stops
then
rotate
the

to
completely
remove
the
enclosure
from
the

Power
cord
connection
CAUTION:
The
power
connection
must
always
be
disconnected
prior
to
removal
of
a
PSU
from
the
enclosure.
To
connect
the
power
cord,
do
the
following:
1.
Observe
all
safety
and
ESD
precautions
listed
in
the
Safety
and
Warranty
Guide.
2.
Attach
a
power
cord
for
the
installed
PSU.
The
Power

LED
(see
1
in
for
the
PSU
will
blink
green
when
AC
main
power
is
present.
The
Power

will
illuminate
a

Grounding
checks
The
SMC
-
Storage
Array
must
only
be
connected
to
a
power
source
that
has
a
safety
electrical
earth
connection.
CAUTION:
If
more
than
one
enclosure
is
installed
in
a
rack,
the
earth
connection
to
the
rack
is
even
more
important,
because
the
rack
will
have
a
high
“earth
leakage
current”
(“touch
current”).
Before
powering
on,
the
earth
connection
to
the
rack
must
be
checked
by
an
electrical
engineer
who
is
qualified
in
local
and
National
electrical
standards.
