Introduction Congratulations to your purchase on Xsense Fast Ethernet Switch! The Xsense Fast Ethernet switch provide you the possibility in setting up a small, medium or large size network without encountering bandwidth bottlenecks. The switch is compliant with the IEEE802.
General F eatures of a Switch General features of FES-1800 Switch Compliant with the IEEE802.3 10Mbps specification (10BASE-T) Compliant with the IEEE802.
Front panel FES-1800 Figure 1-1 The switch's front panel displays features LED (light emitting diode) indicators. (See Figure 1-1.) Rear panel FES-1800 Figure 1-2 The rear panel of the switch contains the power socket and Ethernet cable con- nectors.
Quick O verview of Networking Terminology Network Terminology A network is cosisted of multiple interconnected nodes. A node can be a comput- er, a server (that is, a computer dedicated to storing net.
- Check the validity of each signal it receives and discard invalid signal. - Show whether each network node is currently connected, idle, transmiting data, or in half/full duplex. Indicating a collision it gives users an idea on the network's current traffic status, Collisions occur frequently in a Fast Ethernet network.
What Is Fast Ethernet? Historical Background Fast Ethernet was developed in the early 90s to solve the bottleneck problems encountered by older Ethernet networks. Ethernet, however, is a networking tech- nology developed in the early 70s. Ethernet network carries data signal through thick passive cables at a speed of 10Mbp.
How to C onfigure a Fast Ethernet Network? Cable L ength In a Fast Ethernet network, twisted-pair cables have a length limit. No UTP or STP cable can be of more than 100 meters (328 feet). A signal can not be sent between two end nodes through more than 200 meters of twisted pair cable.
Different Network T opologies V aries with users' needs, the switch can be operated as a standalone device or in a multiple-switches environment. Standalone Device When one switch is in use in a network, it is a standalone switch. The switch can only be connected to users' workstations.
Gateway A gateway is a device that connects a network to another, supporting a different protocol than the one currently used (Fast Ethernet in this case).
Installing a Switch Before the Installation Before installing a switch, users must acertain that a proper operating environ- ment is provided for the network.
Connecting Hubs or Other Switches T o make a switch-to-hub or switch-to-switch connection, please do the following: 1. Make sure you have the proper cables: - Use Category 3 UTP (Unshielded T wisted Pair) cables or better for 10BASE- T connections - Use Category 5 UTP cables for 100BASE-TX connections.
The users must consider the following cable requirements prior to connections: - Cables must be of a Category 5 UTP or Category 1 STP or equivalent cable type for a Fast Ethernet network. Such cables feature RJ-45 plugs at both ends and through wiring.
Network M anagement LED Indicators The switch's front panel contains indicators called light emitting diodes or LEDs. LEDs make quick diagnoses on the network's status. They allow users to know, at a glance, the kind of problem the network encounters.
A collision occurs as two end nodes are sending data simultaneously on the network. Collisions are frequent in a Fast Ethernet network. When a collision occurs, the two end nodes stop data transmission but backs up again later on.
- Selecting a location that fits the network's configuration and ensures the switch's safety. - Being aware of cables' physical path and avoiding any interruptions.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Network Technologies FES-1800 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Network Technologies FES-1800 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Network Technologies FES-1800 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Network Technologies FES-1800 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Network Technologies FES-1800, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Network Technologies FES-1800.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Network Technologies FES-1800. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Network Technologies FES-1800 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
