Serial connector
Your computer has two standard serial connectors: serial connector A and serial
connector B.
Some application programs require specific connectors, and some modems function
properly only at certain communication connector addresses. You might need to
use the Configuration/Setup Utility program to change communication connector
address assignments to prevent or resolve address conflicts.
Viewing or changing the serial-connector assignments
Complete the following steps to view or change the serial-connector assignments:
1.
Restart the computer 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 serial connector; then, use the arrow keys to advance through the
available settings.
5. Press Esc twice to return to the Configuration/Setup Utility main menu; then,
select
Save & Exit Setup to exit from the Configuration/Setup Utility main
menu.
Serial connectors
There are two 9-pin, male D-shell serial connectors located on the rear of your
computer, see “I/O connector/port locations - Type 6846 and 6836” on page 30 for
their locations.

Ethernet connector
Your computer comes with an integrated Ethernet controller. This controller
provides an interface for connecting to 10-Mbps or 100-Mbps networks and
provides full-duplex capability, which enables simultaneous transmission and
reception of data on the Ethernet LAN.
To access the Ethernet connector, attach a Category 3, 4 or 5 unshielded
twisted-pair (UTP) cable to the RJ-45 connector on the rear of your computer, see
“I/O connector/port locations - Type 6846 and 6836” on page 30.
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5.
Configuring the Ethernet controller
When you connect your computer to the network, the Ethernet controller
automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network
and then sets the controller to operate at the appropriate rate. In addition, if the
Ethernet connector that your computer is connected to supports auto-negotiation,
the Ethernet controller will set the appropriate duplex state. That is, the Ethernet
controller will adjust to the network data rate, whether the data rate is standard
Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or FDX. The
controller supports HDX and FDX modes at both speeds.
