LAN

The computer has built-in support for Ethernet LAN (10 megabits per

second, 10BASE-T) or Fast Ethernet LAN (100 megabits per second,

100BASE-TX).

This section describes how to connect/disconnect to a LAN.

The Wake-up on LAN function consumes power even when the

system is off. Leave the AC adaptor connected while using this

feature.

The Link speed (10/100 megabits per second) changes automatically

depending on the network conditions (connected device, cable or

noise and so on).

LAN cable types

The computer must be configured properly before connecting to a LAN.

Logging onto a LAN using the computer’s default settings could cause a

malfunction in LAN operation. Check with your LAN administrator regarding

set-up procedures.

If you are using Fast Ethernet LAN (100 megabits per second, 100BASE-

TX), be sure to connect with a CAT5 cable or higher. You cannot use a

CAT3 cable.

If you are using Ethernet LAN (10 megabits per second, 10BASE-T), you

can connect with a CAT3 or higher cable.

Connecting the LAN cable

To connect the LAN cable, follow the steps as detailed below:

Connect the AC adaptor before connecting the LAN cable. The AC

adaptor must remain connected during LAN use. If you disconnect the

AC Adaptor while the computer is accessing a LAN, the system may

hang up.

Do not connect any other cable to the LAN jack except the LAN cable.

Otherwise, malfunctions or damage may occur.

Do not connect any power supplying device to the LAN cable that is

connected to the LAN jack. Otherwise, malfunctions or damage may

occur.

1. Turn off the power to all external devices connected to the computer.
