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) or Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T).
This section describes how to connect/disconnect to a LAN.
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 (10/100/1000 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 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 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.
