6 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. 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.
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 connections (such as
a separate intra- and extranet).
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.
