Universal Serial Bus
The Universal Serial Bus (USB) port is a high-speed serial bus which allows you to connect and daisy-chain 
USB peripherals without taking up precious system resources.
Fax/data modem
Some models have a built-in V.90 56Kbps PCI fax/data modem.
WARNING:
This modem port is not compatible with digital phone lines.  Plugging this modem into a digital 
phone line will damage the modem.
To use the fax/data modem port, connect a phone cable from the modem port to a telephone jack.
Start your communications software program.  See your communications manual for instructions.
Built-in network feature (optional)
Available on selected models, the built-in network feature allows you to connect your computer to an Ethernet-
based (10BaseT and 100BaseT) network.

To use the network feature, connect an Ethernet cable from the network jack on the rear of the computer to a 
network jack or hub on your network.  Then configure network settings for your computer.
NOTE: Contact your network or system administrator for information on how to configure your computer to 
work in your network environment.
Fast infrared
The computer’s fast infrared (FIR) port allows you to do wireless data transfer with other IR-aware computers 
and peripherals such as infrared printers.  The infrared port can transfer data at speeds of up to four megabits 
per second (Mbps) at a distance of up to one meter.
To use FIR, position two IR-aware devices such that their IR ports are no more than one meter apart and offset 
no more than 15 degrees.
When the two computers are in position, simply begin the data transfer as you normally would.  See your file 
transfer software for details.

PC Card slot
There is a type II/I CardBus PC Card slot found on the right panel of the computer.  This slot accepts a credit-
card-sized card that enhances the usability and expandability of the computer.
PC Cards (formerly PCMCIA) are add-on cards for portable computers, giving you expansion possibilities long 
afforded by desktop PCs.  Popular type II cards include flash memory, SRAM, fax/data modem, LAN and SCSI 
cards.  CardBus improves on the 16-bit PC card technology by expanding the bandwidth to 32 bits.
ZV (Zoomed Video) support allows your computer to support hardware MPEG in the form of a ZV PC card.
NOTE: 
Refer to your card’s manual for details on how to install and use the card and its functions.
Inserting a PC Card
NOTE: 
A slot protector card is installed in the PC Card slot.  Remove it before you insert your PC Card.
Insert the card into the desired slot and make the proper connections (e.g., network cable), if necessary.  See 
your card manual for details.
Ejecting a PC Card
Before ejecting a PC Card:
1.
Exit the application using the card.
2.
Left-click on the PC Card icon on the taskbar and stop the card operation.
