4 network adapter

To attach your computer to a network or broadband device, connect one end of a

connector

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.

NOTE: 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).

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.

5 network activity light Flashes a yellow light when the computer is transmitting or receiving network

data. A high volume of network traffic may make this light appear to be in a steady
