to as
the subsystem,
consists
of
an
HP

4CT
Disc
Drive
(an
HP
7914
Disc
Drive
mounted
in
an
HP
9221

style
cabinet)
along
with an
integral
HP
9144A
Tape
Drive.
The
subsystem
is
designed
for
connection
to
the
Hewlett-Packard
Interface
Bus
(HP-IB)*.
The
disc
and
tape drives
have
separate
HP-IB
connections,
but
may
be
connected
to
the host
via
a
common
HP-IB
cable.
Two
1
-metre
HP-IB
cables are supplied.
Although
the
HP
7914CT
subsystem
contains
an
HP
7914
Disc
Drive and an
HP
9144A
Tape
Drive
in
one
cabinet,
it
should be noted that they
must
be considered
as
separate devices
when
configuring
a
computer
system.
The
tape drive has
its
own
Power
Distribution
Unit (PDU).

CAUTION
As
the tape drive obtains

via
the
disc
drive's
PDU,
ensure
that

DOCUMENTATION
The
following
documentation
is
supplied:
The
HP
7914's
Power
Distribution
Unit
(PDU)
supplies
switched
power
to
the
disc
drive
and
unswitched
power
to
the
tape
drive
via
a
CEE-

female
receptacle
mounted
on
the top
of the
PDU. The
subsystem
is
supplied
with
three
power
cords,
two
are suitable for
use in
the
country
of destination
and one
is
an
internal
cable used to
connect
the
HP
9144A
to
the
disc
drive's
PDU. Of
the
two
local
use
power
cords,
one
is
used
to
connect
the
disc drive's
PDU
to
the
line
supply
and
the other
is
a
spare.
