Setting Up Your Studio One
Connect the Network Cable
(Optional)
A network connection is not required to
complete this computer setup, but if you have
an existing network or Internet connection
that uses a cable connection (such as a home
cable modem or Ethernet jack), you can connect
it now.
Use only an Ethernet cable (RJ45 connector).
Do not plug a telephone cable (RJ11 connector)
into the network connector.
To attach your computer to a network or
broadband device, connect one end of a
network cable to either a network port or a
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.
