Modem Port
The RJ-11 modem port with two pins is smaller than the RJ-45 LAN port and supports a standard
telephone cable. The internal modem supports up to 56K V.90 transfers. The built-in connector allows
convenient use without additional adapters.
IMPORTANT! The built-in modem does not support the voltage used in digital phone
systems. Do not connect the modem port to a digital phone system or else damage
will occur to the Notebook PC.
2.0
USB Port (2.0/1.1)
The Universal Serial Bus is compatible with USB 2.0 or USB 1.1 devices such as keyboards, pointing
devices, video cameras, modems, hard disk drives, printers, monitors, and scanners connected in a
series up to 12Mbits/sec (USB 1.1) and 480Mbits/sec (USB 2.0). USB allows many devices to run
simultaneously on a single computer, with peripherals such as USB keyboards and some newer moni-
tors acting as additional plug-in sites or hubs. USB supports hot-swapping of devices so that peripher-
als can be connected or disconnected without restarting the computer.
LAN Port
The RJ-45 LAN port with eight pins is larger than the RJ-11 modem port and supports a standard
Ethernet cable for connection to a local network. The built-in connector allows convenient use without
additional adapters.
1394 Port
IEEE1394 is a high speed serial bus like SCSI but has simple connections and hot-plugging capabilities
like USB. The interface IEEE1394 has a bandwidth of 100-400 Mbits/sec and can handle up to 63 units
on the same bus. IEEE1394 is also used in high-end digital equipment and should be marked “DV” for
Digital Video port.
Air Vents
The air vents allow cool air to enter and warm air to exit the Notebook PC.
IMPORTANT! Make sure that paper, books, clothing, cables, or other objects do not
block any of the air vents or else overheating of the Notebook PC may occur.
