About Your Computer
Plug a standard PS/2 mouse into the green mouse connector.
Turn off the computer and any attached devices before you
connect a mouse to the computer. If you have a USB mouse,
plug it into a USB connector.
Use the IEEE 1394 connector for high-speed data devices
such as digital video cameras and external storage devices.
The network activity light is on (flashing) 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 on state.
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.
NOTICE:
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.
• Green — A good connection exists between a 10-Mbps
network and the computer.
• Orange — A good connection exists between a 100-Mbps
network and the computer.
• Yellow — A good connection exists between a 1000-Mbps
(or 1-Gbps) network and the computer.
• Off — The computer is not detecting a physical
connection to the network.
Use the (black) surround sound connector to attach
multichannel-capable speakers.
