About Fast Ethernet
As the demand for desktop video, multimedia devel-
opment, imaging, and other speed-intensive applica-
tions continues to rise, the need for high performance,
fault tolerant LAN technology will become more criti-
cal.
Standard Ethernet, which has been the most popular
networking technology to date with a maximum data
throughput of 10 Megabits per second, is becoming
insufficient to handle the latest video, multimedia, and
other speed-intensive Client/Server LAN applications.
Among the solutions to the problem of network speed,
Fast Ethernet has emerged as the most viable and
economical. Capable of sending and receiving data at
100 Megabits per second, it is more than fast enough
to handle even the most demanding video and other
real-time applications.
Although there are a number of different competing
Fast Ethernet implementations, 100BaseTX is by far
the most popular. Operating on two pairs of Category
5 unshielded twisted-pair (UTP) cabling, 100BaseTX
supports high speed signaling and is relatively inex-
pensive. Because it uses four wires for data transmis-
sion and the same packet format, packet length, error
control, and management information as 10BaseT,
100BaseTX can be made to communicate with slower
10BaseT equipment when routed through a switch.
This backward compatibility is one of 100BaseTX's
major advantages over other forms of Fast Ethernet; it
allows critical, speed-dependent network segments to
be upgraded to 100BaseTX speeds as needed without
re-wiring, refitting, and retraining an entire site.
Networks can now mix both slow and fast network
segments for different users or departments.

Publishing, R&D, video, multimedia, or accounting
departments can enjoy a 100Mbps pace, while other
corporate segments can operate at slower and more
affordable 10Mbps speeds.
Every 10/100 RJ-45 port on your Analog Router is
capable of running at either 10Mbps or 100Mbps,
allowing you to mix and match economical 10BaseT
hardware with high performance 100Mbps network
cards, hubs, switches, and other equipment.
BeforeYou Begin
Before you install your EtherFast 10/100 4-Port
Analog Router, you should take careful consideration
and ensure that several requirements have been met on
your network.
The router supports 10Mbps or 100Mbps connections.
It also supports multiple external modem connections.
Please be sure that your network adapters are installed
properly and working, you have a separate telephone
line and an Internet Service Provider (ISP) account for
every modem you plan to use. You must have or obtain
the access phone number, user account and the pass-
word for each of your ISP accounts. If you were using
a Proxy software previously to connect to the internet,
use the instructions that came with the software to
remove the software from your computer. The modem
router will not work properly if proxy software has
been previously installed.
Workstations on your network must have TCP/IP
installed and configured to obtain an IP address auto-
matically using Dynamic Host Control Protocol
(DHCP). If you are using Windows 95, Windows 98 or
Windows NT, detailed instruction about setting up
TCP/IP on Windows 98 or 95 workstations are includ-
5
router.qxd 12/16/99 12:22 PM Page 11

ed in this guide on page 12. Suggested settings and
instructions for Windows NT are included in the
appendix. Setup, configuration, and troubleshooting of
the TCP/IP protocol under any other operating system
is solely up to the user
Each workstation connected to Analog Router must be
running a Web browser (Netscape Navigator 3.0 or
newer, or Internet Explorer 3.0 or newer) in order to
connect to the Internet. Any browser you use to con-
figure the Analog Router must support HTML 3.2 or
later, and it must support Java and frames.
After the router settings are saved, all you need to do
in order to access the internet is open your browser.
The router will do the rest.

Planning Your Network
The rules that govern how nodes and hubs are distrib-
uted across a network are important to ensure the
integrity of your data. Cabling specifications, distance
limits, and other topology rules must be followed in
order to avoid collisions or data loss.
The Analog Router is equipped with 4 10/100 UTP
ports that can automatically adjust to either 10Mbps or
100Mbps speeds. Each port can operate at either
speed, completely independent of the other ports
speeds, and can be connected to a workstation, file
server, print server, hub, or another node with twisted-
pair cabling.
Although there are different grades of cabling, you
must use EIA 568 Category 5 unshielded twisted-pair
(UTP) for each connection you make, and each cable
should not exceed 100 meters, (328 feet), in length.
Fast Ethernet networks require Category 5 cabling.
Category 5 cabling can be obtained at most computer
stores, or you can crimp your own.
