Quick Reference Guide
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.
Remote management features require use of the onboard
NIC.
It is recommended 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.
