To attach your computer to a network or broadband device, connect one end
connector
of a network cable to either a network jack or your network or broadband device.
Connect the other end of the network cable to the network adapter connector
on your computer. A click indicates that the network cable has been
securely attached.
NOTE: Do not plug a telephone cable into the network connector.
On computers with an additional network connector card, use the connectors
on the card and on the back of the computer when setting up multiple network
