Firewall Software
When you use the computer for e-mail, network, or Internet 
access, it is possible for unauthorized persons to obtain 
information about you, your computer, and your information. To 
protect your privacy, it is recommended that you use
 firewall 
software.
Firewalls monitor all incoming and outgoing traffic on your 
computer by including features such as logging and reporting, 
automatic alarms, and user interfaces for configuring the firewall. 
Your computer comes with preinstalled firewall software. Refer 
to the firewall user guides or contact the
 firewall manufacturer.
✎Under some circumstances a firewall can block access to 
Internet games, interfere with printer or file sharing on a 
network, or block authorized e-mail attachments. To 
temporarily solve the problem, disable the firewall, perform the 
task that you want to perform, and then reenable the firewall. 
To permanently resolve the problem, reconfigure the firewall.

Connecting a USB Device
Universal Serial Bus (USB) is a hardware interface that can be 
used to connect an external device such as a USB keyboard, 
mouse, drive, printer, scanner, or hub to the computer or an 
optional expansion product. 
A hub is a connecting device that can be either powered or 
unpowered. USB hubs can be connected to a USB port on the 
computer or to other hubs. Hubs support varying numbers of 
USB
 devices and are used to increase the number of USB devices 
in the system.
■Powered hubs must be connected to external power.
■Unpowered hubs must be connected either to a USB port 
on
 the computer or to a port on a powered hub.
The 3 USB ports on the computer support USB 2.0-compliant, 
USB 1.1-compliant, and USB 1.0-compliant devices.
Ä
CAUTION: To prevent damage to the USB connectors, use minimal 
force to insert a USB device.

not function unless an operating system that supports USB is 
installed in the computer.
Some USB devices may require additional support software, 
which is usually included with the device. For more information 
and software installation instructions, refer to the user guides 
included with the device.

Connecting a 1394 Device
IEEE 1394 is a hardware interface that can be used to connect a 
high-speed multimedia or data storage device to the computer. 
Scanners, digital cameras, and digital camcorders often require 
a
 1394 connection.
You may have to load device-specific drivers and other software 
before using some 1394 devices. For information about 
device-specific software, refer to the device user guides or to the 
Web site of the device manufacturer or provider.
The computer 1394 port, illustrated below, supports IEEE 1394 
devices.
ÄCAUTION: To prevent damage to the 1394 port connectors, use 
minimal force to insert a 1394 device.
To connect a 1394 device to the computer, slide the 1394 
connector into the 1394 port. (The operating system will issue a
