(FireWire)
connector
(some
models)
There
is
one
4-pin
Institute
of
Electrical
and
Electronics
Engineers
(IEEE)
1394
(FireWire)
connector
on
the
front
of
the
computer
and
one
6-pin
IEEE
1394
(FireWire)
connector
on
the
rear
of
the
computer.
Use
these
connectors
to
connect
IEEE
1394
(FireWire)
devices.
The
following
illustrations
show
the
IEEE
1394
(FireWire)
connectors.

Keyboard
connector
There
is
one
keyboard
connector
on
the
rear
of
the
computer.
Use
this
connector
to
connect
a
PS/2
(non-USB)
keyboard.
The

If
you
attach
a
keyboard
to
this
connector,
Universal
Serial
Bus
(USB)
ports
and
devices
are
disabled
during
the
power-on
self-test
(POST).
Parallel
connector
There
is
one
parallel
connector
on
the
rear
of
the
computer.
Use
this
connector
to
connect
a
parallel
device.
The
following
illustration
shows
a
parallel
connector.

The
parallel
connector
supports
three
standard
IEEE
1284
modes
of
operation:
standard
parallel
port
(SPP),
enhanced
parallel
port
(EPP),
and
extended
capability
port
(ECP).
If
you
configure
the
parallel
port
to
operate
in
bidirectional
mode,
it
supports
the
ECP
and
EPP
modes.
When
the
parallel
connector
is
configured
as
bidirectional,
use
an
IEEE
1284-compliant
cable
that
does
not
exceed
3
meters
(9.8
ft).
Use
the
Devices
and
I/O
Ports
options
in
the
IBM
Configuration/Setup
Utility
program
to
configure
the
parallel
connector
as
bidirectional.
