LAN
LAN circuits support 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.
CAUTION: Do not install or remove an optional memory module while
Wake-up on LAN is enabled.
NOTE: Wake-up on LAN does not work without the AC adaptor. Leave it
connected, if you are using this feature.
LAN cable types
CAUTION: 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 administra-
tor 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. You cannot use a CAT3 cable.
If you are using Ethernet LAN (10 megabits per second, 10BASE-T), you can
connect with either a CAT5 or a CAT3.
Connecting cable
To connect the LAN cable, follow the steps below.
CAUTION: Connect the AC adaptor before connecting the LAN cable.
The AC adaptor must remain connected during LAN use. If you discon-
nect the AC Adaptor while the computer is accessing a LAN, the system
may hang up.
1. Turn off the power to the computer and to all external devices connected to
the computer.
