(1.75″)
of
a
standard
19-inch
rack
using
an
optional

the
following
components
on
the
front
of
the
unit:
Status

the
7212
Storage
Enclosure
is
powered
on
and
no

exists
for
the
enclosure.
v
The

Switches
The

SCSI
address
switches
are
used
to
identify
the
installed
storage
devices
to
the
host
system.
Note:
The
SCSI
address
switches
are
supplied
as
part
of
the
device
feature
kits
since
the
various
supported
devices
each
have
unique
requirements
for
the
address
switches.
Therefore
if
no
drive
is
installed
in
a
device
bay,
then
no
SCSI
address
switch
is
installed
for
that
bay.
Audio
Jack
Connectors
If
a
DVD-ROM
or
DVD-RAM
drive
is
installed
in
Bay
B,
the
audio
jack
connectors
3
can
be
used
to
attach
the
drive
to
a
stereo
amplifier.
Note:
The
audio
jack
connectors
are
supplied
as
part
of
the
device
feature
kits,
since
the
various
supported
devices
each
have
unique
requirements
for
the
audio
jack
connectors.
The
audio
jack
connectors
are
supplied
only
with
the
DVD-ROM
Drive
and
the
DVD-RAM
Drive
feature
kits.
Audio
jack
connectors
can
only
be
used
for
a
DVD-ROM
drive
or
DVD-RAM
drive
installed
in
device
bay
B
(see
Figure
1
on
page
1).
If
a
DVD-ROM
drive
or
DVD-RAM
drive
is
not
installed
in
device
bay
B,
no
audio
jack
connectors
are
installed
in
the
7212
Storage
Enclosure.
Cooling
Fans
The
7212
Storage
Enclosure
utilizes
two
internal
cooling
fans
(4
and
6)
to
regulate
the
internal
temperature
of
the
enclosure.
Air
exits
the
7212
Storage
Enclosure
at
the
two
cooling
fan
locations.
Note:
To
ensure
proper
operation,
place
the
7212
Storage
Enclosure
so
that
the
cooling
fan
exits
at
the
rear
of
the
enclosure
and
the
air
inlet
holes
at
the
front
of
the
enclosure
have
sufficient
clearance
to
ensure
airflow.

Service
Guide
SCSI
Bus
Connectors
The
7212
Storage
Enclosure
provides
two,
68
pin,
rear
mounted,
SCSI
bus
connectors
5
for
attaching
the
7212
Storage
Enclosure
to
the
host
SCSI
bus.
These
two
external
SCSI
connectors
represent
the
two
ends
of
the
internal
SCSI
bus
cables.
The
internal
SCSI
bus
cable
can
be
configured
to
support
either
a
single
SCSI
bus
with
one
host
system
or
with
a
split
SCSI
bus
allowing
SCSI
connections
to
two
hosts.
Devices
installed
in
the
two
enclosure
device
bays
are
attached
to
the
internal
SCSI
bus
cables
so
that
the
installed
devices
can
be
on
a
single
or
split
SCSI
bus.
Note:
The
SCSI
interface
mode
(Low
Voltage
Differential
or
Single
Ended)
that
the
7212
Storage
Enclosure
will
operate
in,
is
dependent
on
the
type
of
drives
installed
in
the
7212
Storage
Enclosure
and
the
host
system
SCSI
adapter
type.
Fault
Signal
USB
Port
The
rear
of
the
7212
Storage
Enclosure
has
a
Fault
Signal
USB
Series
B
Port
7.
This
port
is
provided
for
installations
that
have
provisions
for
remote
fault
monitoring
of
devices.
If
the
7212
Storage
Enclosure
experiences
a
fault
condition
(power
loss
or
fan
failure)
the
Pin
2
signal
of
the
USB
port
will
go
from
a
high
