REAR PANEL COMPONENTS

DC Power Jack
The DC power jack allows you to plug in the AC adapter
or the optional Auto/Airline adapter to power your
Tablet PC and charge the internal Lithium ion Battery.
Modem (RJ-11) Telephone Port
The Modem (RJ-11) telephone port is for attaching
a telephone line to the internal multinational 56K
modem.
The internal multinational modem is not
intended for use with Digital PBX systems.
Do not connect the internal modem to a
Digital PBX as it may cause serious damage
to the internal modem or your entire
LifeBook T Series Tablet PC. Consult your
PBX manufacturer's documentation for
details. Some hotels have Digital PBX
systems. Be sure to find out BEFORE you
connect your modem.
The internal modem is designed to the
ITU-T V.90 standard. Its maximum speed
of 53000 bps is the highest allowed by
FCC, and its actual connection rate
depends on the line conditions. The
maximum speed is 33600 bps at upload.

The two USB 2.0 ports (one on rear panel and one on
left-side panel) allow you to connect Universal Serial
Bus devices. See "Universal Serial Bus Ports" on page 54.
Infrared Port
The fast IrDA compatible port allows you to communi-
cate with another IrDA-compatible infrared device
without a cable. (See "Infrared Port" on page 54.)
LAN (RJ-45) Port
The internal LAN (RJ-45) port is used for an internal
GigaLAN Ethernet (10/100/1000 Base-T/TX) connec-
tion. See "Internal LAN (RJ-45) jack" on page 54.
External Video Port
The external monitor port allows you to connect an
external monitor or LCD projector. For simultaneous
display, this model supports XGA (max. 1024 x 768) or
SXGA+ (max 1400 x 1050) resolutions. When running
CRT only, UXGA (max 1600 x 1200 resolution) is
supported. Note that when the optional Port Replicator
is attached to the system, you must use the external
monitor port on the Port Replicator rather than the port
on the system. See "External Video Port" on page 55.
