Connecting the Network Cable
A network cable has an 8-pin RJ-45 network connector at each
end and may contain noise suppression circuitry, which prevents
interference with TV and radio reception. To connect the cable:
1. Identify the RJ-45 network jack 1 on the notebook.
2. Orient the end of a network cable with noise suppression
circuitry 2 toward the notebook.
3. Plug the network cable into the notebook RJ-45
network jack 3.
4. Plug the other end of the cable into the network RJ-
45 jack 4.
Connecting a network cable
WARNING: To reduce the risk of electric shock, disconnect
the network cable before accessing an internal compartment of the
notebook. Internal compartments include the memory compartment
and the battery and hard drive bays.
