NOTICE:
Do not plug a telephone cable into the network adapter connector.
Use the network adapter connector 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, and then 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.
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
connections (such as a separate intra- and extranet).
NOTE:
Dell recommends that you use Category 5 wiring and connectors for your
network. If you must use Category 3 wiring, force the network speed to 10 Mbps to
ensure reliable operation.
