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 inexpensive. Because it uses four wires for data transmission 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. 4 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. Before You 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 password 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 automatically 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 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 configure 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. 6 Planning Your Network The rules that govern how nodes and hubs are distributed 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 twistedpair 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. 7 Here are some important cabling rules to follow: · Computers should never be connected directly together on a network. They should always be connected to a hub. · The maximum cable length from a node to a 10BaseT or 100BaseTX repeater, switch, or hub is 100 meters (328 feet). · Only two 100Mbps Fast Ethernet hubs can be cascaded, (or uplinked), together. To cascade more than two 100Mbps hubs, a switch must be used. · The maximum distance between 2 100BaseTX hubs (or the Analog Router and a 100BaseTX hub) without a switch is 5 meters (16.4 feet). · The maximum distance between 2 10BaseT hubs, (or a 10BaseT hub and an Analog Router), is 100 meters (328 feet). 8 Hardware Setup 1. Remove the EtherFast 10/100 4-Port Analog Router from its packaging. The area you plan to place the router must be well ventilated. Leave at least 4" behind the router to make room for the cable connections. Leave 2" on each side and 1" on top to ensure good ventilation. 2. Connect the AC adapter to the Analog Router DC12V power input, and plug the other end into the nearest wall outlet. It will take between 10 and 30 seconds for the router to fully boot up. 3. Connect up to four external modems to the Modem connectors on the back of Modem Router (4 RJ-45 ports to the right of the 9-pin console port) using the provided RJ-45 to serial cables. Do NOT connect your modems to the Ethernet ports on the router. If you find that you need extra cabling or adpaters, you can find what you need at your local Linksys vendor. 4. Connect your workstations or hubs to the four 10/100 auto-sensing ports on the back of the router. The port closest to the AC adapter can be readily used to uplink to another hub. See page 11 for uplinking information. 5. If you want to use Command Line Interface, connect a PC or terminal to the console port using the supplied serial null modem cable. 9 Connecting Nodes to the Analog Router The Analog Router can be connected to either 10Mbps or 100Mbps PCs, workstations, file servers, print servers, or other hardware. When powered up, each of the router's 10/100 ports will automatically a ...
