second
power
supply-fan
unit
(because
the
storage
subsystem
requires
that
at
least
one
power
supply-fan
unit,
functioning
or
not,
must
be
present
in
the
storage
subsystem
at
all
times).
Releasing
a
component
lever
Each
component
is
secured
into
the
storage
subsystem
chassis
by
two
cam
lock
levers
mounted
to
the
component.
The
lever
engages
with
a
pin
on
the
storage
subsystem
chassis
to
pull
the
component
securely
into
the
chassis.
The
levers
are
locked
in
place
by
spring-loaded
latches.
The
control
components
have
the
levers
on
the
same
side.
The
power
supply-fans
and
the
interconnect-battery
unit
have
the
one
lever
mounted
to
the
top
of
the
component
and
one
lever
mounted
to
the
bottom
of
the
component.
shows
a
component
lever
and
the
latch
that
secures
the
lever.
The
top
view
shows
the
lever
in
the
closed
and
latched
position.
The
bottom
view
shows
the
lever
in
the
released
position.
To
release
both
latches
on
a
component
and
remove
the
component:
1.
Push
the
latches
to
the
side
until
the
latches
release
the
levers.
Do
not
proceed
with
the
next
step
until
you
have
released
both
levers
from
the
latches.
2.
Rotate
both
levers
out
simultaneously.
Ensure
that
the
levers
are
completely
free
of
the
pins.
Then
place
one
hand
under
the
component
and
use
the
levers
to
pull
the
component
from
the
DS4800
Storage
Subsystem.
To
replace
a
component
and
lock
the
latches:
1.
With
both
levers
rotated
out
perpendicular
to
the
face
of
the
component,
slide
the
back
of
the
component
into
the
appropriate
slot.
