System Introduction1-3 1.2 Ports The computer’s ports allow you to connect peripheral devices to your computer just as you would to a desktop PC. The main ports are found on the computer’s rear panel. The computer’s left panel contains the computer’s multimedia ports and PC card slots. 1.2.1 Rear Panel Ports The computer’s rear panel contains the computer’s main ports and connectors as shown in the illustration below. 1 DC-in Port 2 PS/2 Port 3 Serial Port 4 Parallel Port 5 Mini Dock Connector 6 External CRT Port 7 USB Port 8 Infrared Port Figure 1-2 Rear Port Location Table 1-1 Rear Port Descriptions PortIconConnects to...

1-4Service Guide UNIVERSAL SERIAL BUS (USB) PORT The computer’s USB (Universal Serial Bus) port located on the rear panel allows you to connect peripherals without occupying too many resources. Common USB devices include the mouse and keyboard. FAST INFRARED (FIR) PORT The computer’s FIR (fast infrared) port located on the rear panel allows you to transfer data to IR- aware machines without cables. For example, you can transfer data between two IR-capable computers, or send data to an IR-aware printer without using a cable. The infrared port is IrDA-compliant, and can transfer data at speeds of up to 4 megabits per second (Mbps) at a distance of up to one meter. To use the infrared port, position two IR-aware devices such that their IR ports are no more than one meter apart and offset no more than 15 degrees. W hen the two computers are in position, simply begin the data transfer as you normally would. See your file transfer software for details. 1.2.2 Left Panel Ports The computer’s left side panel contains the computer’s multimedia ports and PC card slots, as shown in the illustration on the next page. 1 PC Card Slots 2 Microphone-in/Line-in Port 3 Speaker-out/Line-out Port Figure 1-3 Left Port Location 1 23
