SCSI
Interface
card
switches
Figure
29
shows
the
switches
on
the
SCSI
Interface
card.
The
SCSI
Interface
card
contains
the
following
switches
that
are
accessible
to
the
operator.
Note:
Switch
configuration
is
only
valid
on
the
SCSI
Interface
card-1
and
the
configuration
on
the
SCSI
Interface
card-2
is
ignored.
Therefore,
the
SCSI
Interface
card
must
be
placed
in
the
left
side
viewing
it
from
the
rear
in
single
SCSI
Interface
card
configuration.
Drive
autostart
switch-1
1
The
disk
drive
motors
are
controlled
by
the
combination
of
this
switch
and
the
drive
autostart
switch-2
2
.
When
this
switch
is
set
to
off,
and
the
drive
autostart
switch-2
2
is
set
to
on,
the
disk
drive
motors
do
not
start
until
you
issue
a
START
MOTOR
command.
The
timing
sequence
of
the
disk
motor
startup
is
under
the
control
of
the
host
system
software.
When
this
switch
is
set
to
on,
and
the
drive
autostart
switch-2
2
is
set
to
off,
the
disk
drives
are
set
to
delay
motor
start
mode.
The
disk
motor
startup
delay
time
is
different
for
each
disk
drive
and
is
usually
computed
by
multiplying
12
seconds
by
its
SCSI
ID.
For
example,
the
disk
drive
motor
of
a
disk
drive
whose
SCSI
ID
is
2
starts
24
(2x12)
seconds
after
power
is
applied
to
the
2104
Model
DS4
or
Model
TS4.
When
this
switch
is
set
to
off,
and
the
drive
autostart
switch-2
2
is
set
to
off,
the
disk
drives
are
set
to
normal
start
mode.
The
disk
drive
motors
start
when
power
is
applied
to
the
2104
Model
DS4
or
Model
TS4.
The
effect
of
both
this
switch
and
the
drive
autostart
switch-2
2
being
set
to
on
is
undefined.
