Introduction Congratulations on purchasing your new EtherFast 10/100 Dual-Speed Switch for your network's 10/100 migration needs. Ready to run right out of the box, the EtherFast 10/100 Dual-Speed Switch is the easiest, most flexible way to boost your network's performance with full duplex data transfer and dedicated bandwidth to each of [...]

About Fast Ethernet As the demand for desktop video, multimedia development, imaging, and other speed-intensive applications continues to rise, the need for high per- formance, fault tolerant LAN technology will become more critical. Standard Ethernet , which has been the most popular networking technolo- gy to date with a maximum data throughput o[...]

Switched Ethernet , by contrast, is closer to the notion of individual tele- phone lines: a switching hub examines the incoming MAC addresses of network packets and forwards them directly to their destinations without repetition, reducing bandwidth waste and resulting in more predictable net- work performance. Each node receives its own full-speed [...]

Her e are some scenarios in which a switch can be applied: · Speeding up a 10BaseT Network On a 10BaseT network, you might connect users to one of the switch's 10/100 ports and the file server to the other , allowing the server to service more users faster because it enjoys its own switched pipeline into the net- work. · Mixing 10BaseT with [...]

Planning Y our Network The rules that govern how switches are distributed in Fast Ethernet are slightly different from 10BaseT networking rules. Cabling specifications, distance limits, and other topology rules must be followed in order to avoid network collisions and data loss. Here are the most important rules to follow: · 100BaseTX requires fou[...]

The diagram below shows one possible configuration of a 12-Port Switch in a Fast Ethernet environment; if you have an 16 or 24-Port Switch, the configura- tion remains the same. Note that like all Fast Ethernet network hardware, the switch requires Category 5 UTP network cabling, which is available at most computer stores. In this example, each wor[...]

Installing the Switch P ackage Contents Carefully remove the switch from its packaging. Make sure that you received all of the items listed below . If any items are missing or damaged, contact your Linksys dealer for replacement part(s). · EtherFast 10/100 Dual-Speed, Autosensing 12, 16 or 24-Port Switch · Rack Mounting Hardware · AC Power Cord [...]

Each switch can be connected to workstations, PCs, file servers, hubs, repeaters, bridges, or other switches. Each cable connected to the switch must be a Category 5 UTP network cable with RJ-45 tips, and should not exceed 100 meters (328 feet), in length. Ready-to use network cables of vari- ous lengths can be purchased at most computer stores. Se[...]

11 Expanding Y our 10/100 Dual-Speed Switches The EtherFast 12, 16 and 24-Port Switches are equipped with an expansion slot in the back of the switch into which expansion modules with different features can be inserted. The 100BaseFX Fiber Optic Distance Extender Module allows you to con- nect your EtherFast 10/100 Dual-Speed Switch to other switch[...]

Installing the Fiber Expansion Modules T o install an expansion module on the back of the EtherFast 10/100 Dual- Speed Switches, follow these instructions: 1. Power off your Switch and remove the AC power cord before begin- ning. If the switch is installed in a rack, it is recommended to remove the switch from the rack temporarily and reinstall it [...]

Fiber Optic Modules There are different 100BaseTX fiber add on modules available switches: Modules with ST or SC-T ype Fiber Optic Distance Extender Ports (can used on the back of all the switches): DSSXFXST ST -T ype Single-P ort Fiber Module DSSXFXSC SC-T ype Single-P or t F iber Module The following chart shows the distance limitations when usin[...]

15 T wisted-Pair Wiring There are different grades, or categories, of twisted-pair cabling. Category 5 is the most reliable and widely compatible, and is required for Fast Ethernet networks. Y ou can buy Category 5 cabling that is pre-crimped, or you can crimp your own. Category 5 cables can be purchased or crimped as either straight-through or cro[...]
