Device Ports
Your LifeBook notebook comes equipped with multiple
ports to which you can connect an external device
including: disk drives, keyboards, modems, printers, etc.
COMMUNICATIONS PORTS
Your LifeBook has a Modem jack (RJ-11) and a LAN
jack (RJ-45) to accommodate external communications.
Modem (RJ-11) Telephone Jack
The modem (RJ-11) telephone jack is used for your
internal modem. To connect the telephone cable follow
these easy steps: (Figure 4-14)
1. Align the connector with the port opening.
2. Push the connector into the port until it is seated.
3. Plug the other end of the telephone cable into a
telephone outlet.

LAN PORT
This port allows you to connect a LAN (RJ-45) cable for
high-speed network or broadband connections (e.g.,
DSL, cable modem). (Figure 4-15)

IEEE 1394 JACK
The 4-pin IEEE 1394 (Firewire) jack is a high-speed
interface (400 Mbps) that can be used to transfer large
amounts of data between your notebook and a Firewire
peripheral such as a digital camera, external hard drive,
or video camera. Hot-swappable and plug-n-play, it is
much faster than USB 1.1, CardBus, or parallel port. To
connect a 1394 device, follow these steps: (Figure 4-16)

UNIVERSAL SERIAL BUS (USB) 2.0 PORTS
The five Universal Serial Bus (USB) 2.0 ports allow you
to connect USB devices such as game pads, pointing
devices, keyboards and speakers. There is one USB 2.0
port on the right side, and four on the rear panel.
(Figure 4-17).
USB 2.0 is downward-compatible with USB 1.1 devices,
so older USB devices will work with these ports. USB 2.0
is a much faster design, running forty times faster than
USB 1.1. To connect a USB device follow these steps:
Do not connect the internal modem to a
Digital PBX as it may cause serious damage
to the modem or your LifeBook notebook.
It should be noted that some hotels use
the Digital PBX systems, please be sure to
find out BEFORE you connect your
modem. Consult your PBX manufacturer’s
documentation for more information.
The internal modem is designed to the
ITU-T V.90 standard. Its maximum speed
of 53000bps is the highest allowed by the
FCC, and its actual connection rate
depends on the line conditions. The
maximum speed is 33600bps at upload.
The 1394 port in this system uses a four-
pin configuration. If you intend to
interface with devices which have a six-pin
configuration, you will need to purchase
an adapter.
Note that only the individual horizontal
USB port on the right rear of the system
can be used to connect an infrared remote
control receiver that is required when
using the optional Media Center Edition
remote control.
