–
Pin
5
has
three
states:
off
(ground),
on
(3.3
V),
and
alternating
(between
off
and
on).
Pin
5
will
be
off
if
the
drive
does
not
detect
light
on
the
Fibre
Channel
connector,
if
(while
communicating
as
an
L_port)
the
drive
does
not
complete
the
Loop
Initialization
Protocol
(LIP),
or
if
(while
communicating
as
an
N_port)
the
drive
does
not
complete
logging
in
to
the
host
or
switch.
Pin
5
will
be
on
if
the
drive
detects
light,
successfully
completes
the
LIP
process,
or
logs
in
to
another
port.
After
the
drive
has
completed
the
LIP
process,
the
pin
will
be
alternating
when
the
drive
is
receiving
SCSI
commands,
and
the
pin
will
be
on
when
the
drive
is
not
receiving
SCSI
commands.
–
Pin
6
indicates
that
the
drive
detects
light.
If
pin
6
is
on
but
pin
5
is
off,
this
could
indicate
communication
problems
across
the
fiber
cable.
–
If
the
drive
is
installed
in
an
enclosure,
pins
5
and
6
may
be
used
to
support
external
indicators,
such
as
light-emitting
diodes
(LEDs),
on
the
enclosure.
Note:
If
indicators
are
used
on
an
enclosure,
the
drive
does
not
report
error
codes
8
and
F
(Fibre
Channel
problems)
to
the
single-character
display.
Instead,
pins
5
and
6
signal
to
the
indicators
that
there
is
a
problem.
v
Pin
9
is
ground.
To
set
the
AL_PA:
__
1.
Determine
an
unused
AL_PA
for
the
drive
and
refer
to
Table
3
on
page
18
for
its
corresponding
LID.
__
2.
Locate
the
LID/status
connector
on
the
drive
(see
2
in
Figure
8).
__
3.
Place
jumpers
on
pins
1,
2,
3,
4,
7,
and
8
as
shown
in
Table
3
on
page
18.
By
using
hard
addressing,
you
can
specify
one
of
62
valid
AL_PAs
for
the
drive.
If
you
place
jumpers
on
the
four
top
and
bottom
pins
on
the
right
(a
total
of
eight
pins),
the
drive
gets
the
AL_PA
from
a
field
in
its
vital
product
data
(VPD).
(A
tape
library
can
set
the
AL_PA
in
the
VPD
through
the
LDI
interface.)
If
you
do
not
place
jumpers
on
any
pins,
the
drive
uses
soft
addressing
to
determine
the
AL_PA.
Figure
8.
Setting
the
Loop
ID
and
the
AL_PA.
The
feature
switches
are
located
on
the
bottom
of
the
drive.
