Keyboard Mouse Parallel Serial RS-485 (ASM interconnect) USB 2 USB 1 Video Ethernet External SCSI knockout 1 2 Parallel port Optional external serial knockout Two cable-restraint brackets are on the tower model on the rear of the server. After you connect the cables to the selected devices, you can use these cable-restraint brackets to manage the cable routing. Route the power cords through the power-cord restraint bracket on the bottom. Route the remaining cables (for example, the cables that are connected to the I/O ports) through the I/O cable-restraint bracket on the top. Your server has one parallel port. This port 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 parallel-port assignments You can use the built-in Configuration/Setup Utility program to configure the parallel port 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. To view or change the parallel-port assignment: 1. Restart the server and watch the monitor screen. 2. When the message Press F1 for Configuration/Setup appears, press F1. Note: The Devices and I/O Ports choice appears only on the full configuration menu. If you set two levels of passwords, you must type the administrator password to access the full configuration menu. 3. From the main menu, select Devices and I/O Ports; then, press Enter. 4. Select the parallel port; then, use the arrow keys to advance through the available settings. Note: When you configure the parallel port as bidirectional, use an IEEE 1284-compliant cable. The maximum length of the cable must not exceed 3 meters (9.8 ft). 5. Select Save Settings; then, select Exit Setup to exit from the Configuration/Setup Utility main menu. Chapter 4.

Two
cable-restraint
brackets
are
on
the
tower
model
on
the
rear
of
the
server.
After
you
connect
the
cables
to
the
selected
devices,
you
can
use
these
cable-restraint
brackets
to
manage
the
cable
routing.
Route
the
power
cords
through
the
power-cord
restraint
bracket
on
the
bottom.
Route
the
remaining
cables
(for
example,
the
cables
that
are
connected
to
the
I/O
ports)
through
the
I/O
cable-restraint
bracket
on
the
top.
Parallel
port
Your
server
has
one
parallel
port.
This
port
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
parallel-port
assignments
You
can
use
the
built-in
Configuration/Setup
Utility
program
to
configure
the
parallel
port
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.
To
view
or
change
the
parallel-port
assignment:
1.
Restart
the
server
and
watch
the
monitor
screen.
2.
When
the
message
Press
F1
for
Configuration/Setup
appears,
press
F1.
Note:
The
Devices
and
I/O
Ports
choice
appears
only
on
the
full
configuration
menu.
If
you
set
two
levels
of
passwords,
you
must
type
the
administrator
password
to
access
the
full
configuration
menu.
3.
From
the
main
menu,
select
Devices
and
I/O
Ports
;
then,
press
Enter.
4.
Select
the
parallel
port;
then,
use
the
arrow
keys
to
advance
through
the
available
settings.
Note:
When
you
configure
the
parallel
port
as
bidirectional,
use
an
IEEE
1284-compliant
cable.
The
maximum
length
of
the
cable
must
not
exceed
3
meters
(9.8
ft).
5.
Select
Save
Settings
;
then,
select
Exit
Setup
to
exit
from
the
