Setting Up Your Inspiron Desktop
Connect the Network Cable
(Optional)
A network connection is not required to
complete your computer setup, but if you have
an existing network or Internet connection that
uses a cable connection (such as a broadband
device or Ethernet jack), you can connect
it now.
NOTE: Use only an Ethernet cable to
connect to the network connector
(RJ45 connector). Connect the telephone
cable only to the modem connector
(RJ11 connector) and not to the network
connector (RJ45 connector).
To connect your computer to a network or a
broadband device, connect one end of the
network cable to the network port or the
broadband device. Connect the other end of
the network cable to the network connector
(RJ45 connector) on the back panel of your
computer. A click indicates that the network
cable has been securely attached.
