LAN
The computer has built-in support for Ethernet LAN (10 megabits per
second, 10BASE-T) and Fast Ethernet LAN (100 megabits per second,
100BASE-TX). This section describes how to connect/disconnect to a LAN.
LAN cable types
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
Do not install or remove a 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 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 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.
