Operating Basics
LAN
The computer has built-in support for Ethernet LAN (10 megabits per
second, 10BASE-T), Fast Ethernet LAN (100 megabits per second,
100BASE-TX) and Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T).
Some models are equipped with a Gigabit Ethernet LAN.
This section describes how to connect/disconnect to a LAN.
LAN cable types
If you are using Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T), be sure to connect with a CAT5E cable or higher. You
cannot use a CAT3 or CAT5 cable.
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.
Connecting LAN cable
To connect a LAN cable, follow the steps below.
Do not install or remove an optional memory module while Wake-up on
LAN is enabled.
■ 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 (10/100/1000 megabits per second) changes
automatically depending on the network conditions (connected device,
cable or noise and so on).
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.
■ Connect the AC adaptor before connecting a 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.
