4.
While
you
continue
to
push
the
disk
drive
module
into
the
slot,
slowly
close
the
handle
1
until
it
stops
with
a
click.
See
Figure
29.
This
action
pushes
the
module
fully
home.
5.
Verify
that
the
disk
drive
module
that
you
have
just
installed
is
aligned
with
the
sides
of
the
2104
Model
DS4
and
that
no
gap
exists
between
this
module
and
the
modules
that
are
next
to
it.
Verify
also
that
the
front
edge
of
this
disk
drive
module
aligns
with
the
front
edges
of
the
modules
that
are
next
to
it.
If
the
disk
drive
module
is
not
correctly
aligned,
remove
it
(see
“Removing
the
disk
drive
modules
and
dummy
disk
drive
modules”
on
page
5).
Repeat
step
1
on
page
14
through
step
4
to
reinstall
the
disk
drive
module.
6.
Repeat
step
1
through
step
5
for
each
disk
drive
module.
Attention:
Any
slot
that
has
no
disk
drive
module
installed
must
contain
a
dummy
disk
drive
module.
The
dummy
disk
drive
module
ensures
that
the
correct
airflow
is
maintained
around
the
disk
drive
modules
in
the
other
slots.
