To attach your computer to a network or broadband device, connect one
end 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 the back panel of 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 a network connector card, use the connector on the

your network. If you must use Category 3 wiring, force the network
speed to 10 Mbps to ensure reliable operation.
