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.

router.qxd 12/16/99 12:22 PM Page 10

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-

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.
