Operational
Vibration
(Random):
While
in
its
normal
operating
position,
the
DS4000
product
will
continue
operating
when
subjected
to
a
random
vibration
test
using
the
criteria
shown
in
Table
8.
This
test
uses
the
indicated
spectral
power
density
for
30
minutes
in
each
of
the
three
axes.

Heat
output,
airflow,
and
cooling
The
maximum
heat
output
of
the
DS4300
is
390
watts
(1330
BTU/hr).
Each
DS4300
(Model
60U/60X)
and
DS4000
EXP
storage
expansion
enclosures
rack-mounted
unit
requires
an
airflow
of
2.5
m
3
per
minute
(87
ft
3
per
minute).
The
input
air
temperature
to
all
racks
is
recommended
to
be
in
the
range
10°C
through
35°C
(50°F
through
95°F),
with
a
recommended
operating
temperature
of
22°C
(72°F).
When
racks
that
contain
many
DS4300
units
are
to
be
installed
together,
the
following
requirements
must
be
met
to
ensure
that
the
DS4300
units
are
adequately
cooled:
v
Air
enters
at
the
front
of
the
rack
and
leaves
at
the
back.
To
prevent
the
air
that
is
leaving
the
rack
from
entering
the
intake
of
another
piece
of
equipment,
racks
must
be
positioned
in
alternate
rows,
back-to-back
and
front-to-front.
This
arrangement
is
known
as
“Cold
Aisle
/
Hot
Aisle”
and
is
shown
in
Figure
5
on
page
20.
v
Where
racks
are
in
rows,
each
rack
must
touch
the
rack
that
is
next
to
it
to
reduce
the
amount
of
hot
air
that
can
flow
around
from
the
back
of
the
rack
into
the
intakes
of
the
DS4300
units
that
are
in
that
rack.
It
is
recommended
that
Suite
Attach
Kits
be
used
to
completely
seal
any
gaps
that
remain
between
the
racks.
For
details
of
Suite
Attach
Kits,
contact
your
marketing
representative.
v
Where
racks
are
in
rows
front-to-front
or
back-to-back,
a
gap
of
at
least
1220
mm
(48
in.)
must
separate
the
rows
across
the
cold
aisle.
v
To
ensure
correct
airflow
in
each
rack,
the
rack
filler
plates
must
be
installed
in
unused
positions.
Also,
all
the
gaps
in
the
front
of
the
racks
must
be
sealed,
including
the
gaps
between
the
DS4300
units.
