Table 8. Keyboard connector pin-number assignments (continued) Pin I/O Signal 6 N/A Reserved Parallel connector Your server has one parallel connector. This connector supports three standard Institute of Electrical and Electronics Engineers (IEEE) 1284 modes of operation: standard parallel port (SPP), enhanced parallel port (EPP), and extended capability port (ECP). Viewing or changing the connector assignments: You can use the built-in Configuration/Setup Utility program to configure the parallel connector as bidirectional; that is, so that data can be both read from and written to a device. In bidirectional mode, the server supports the ECP and EPP modes. Complete the following steps to view or change the parallel-connector assignment: 1. Restart the server and watch the monitor screen. 2. When the message Press F1 for Configuration/Setup appears, press F1. 3. When the Configuration/Setup Utility menu appears, select Devices & I/O Ports; then, press Enter. 4. Select the parallel connector; then, use the arrow keys to advance through the settings available. Note: When you configure the parallel connector as bidirectional, use an IEEE 1284-compliant cable. The cable must not exceed 3 meters (9.8 feet). 5. Press Esc twice to return to the Configuration/Setup main menu; then, select Save & Exit Setup to exit from the Configuration/Setup Utility main menu. Parallel connector: There is a 25-pin, female D-shell parallel connector on the rear of your server, see "I/O connector locations" on page 72 for the location of this connector. The following table shows the pin-number assignments for the parallel connector. 13 1 25 14 Chapter 5. Installing options 75

Parallel
connector
Your
server
has
one
parallel
connector.
This
connector
supports
three
standard
Institute
of
Electrical
and
Electronics
Engineers
(IEEE)
1284
modes
of
operation:
standard
parallel
port
(SPP),
enhanced
parallel
port
(EPP),
and
extended
capability
port
(ECP).
Viewing
or
changing
the
connector
assignments:
You
can
use
the
built-in
Configuration/Setup
Utility
program
to
configure
the
parallel
connector
as
bidirectional;
that
is,
so
that
data
can
be
both
read
from
and
written
to
a
device.
In
bidirectional
mode,
the
server
supports
the
ECP
and
EPP
modes.
Complete
the
following
steps
to
view
or
change
the
parallel-connector
assignment:
1.
Restart
the
server
and
watch
the
monitor
screen.
2.
When
the
message
Press
F1
for
Configuration/Setup
appears,
press
F1.
3.
When
the
Configuration/Setup
Utility
menu
appears,
select
Devices
&
I/O
Ports
;
then,
press
Enter.
4.
Select
the
parallel
connector;
then,
use
the
arrow
keys
to
advance
through
the
settings
available.
Note:
When
you
configure
the
parallel
connector
as
bidirectional,
use
an
IEEE
1284-compliant
cable.
The
cable
must
not
exceed
3
meters
(9.8
feet).
5.
Press
Esc
twice
to
return
to
the
Configuration/Setup
main
menu;
then,
select

Utility
main
menu.

There
is
a

on
the
