1. Introduction KF-8D dual-speed Fast Ethernet/Ethernet hub is designed to allow easy and flexible migration from 10Mbps Ethernet to 100Mbps Fast Ethernet. The hub complies with IEEE 802.3 and IEEE 802.3u repeater specifications and supports 10Mbps and 100Mbps con- nectivity over UTP cabling in the same hub.
Features • Complies with IEEE 802.3 and IEEE 802.3u standard for Ethernet/Class II Fast Ethernet repeater • Provides a configuration switch (10M/100M/AUTO) to set all 8 TP ports as 10BASE-T ports, 100BASE-TX ports or 10/100 auto-sensing ports.
Dual-speed Hub T echnology Dual-speed hub is designed to support connections with different speeds in the same hub. It makes a network planning simpler, espe- cially when an environment is containing 10Mbps Ethernet and 100Mbps Fast Ethernet technologies.
2. Installation Unpacking Check to see that you have everything before you start the installation. • Installation guide • The hub unit • One AC power adapter for the hub • One wall mount kit Checking AC Power Before you begin the installation, check the AC voltage of your area.
The power socket for the AC power adapter is located on the rear of the hub as shown below: Mounting the Hub The hub can be placed on a desktop as a stand-alone unit. It also can be mounted on a wall. The following procedure describes how to mount the hub onto a wallboard or wood (a stud, heavy wooden paneling, etc.
3. Place the hub against the wall so that the mount bracket fits into the slot bracket on the back of the hub. 4. Slide the hub down until it hangs on the mount bracket.
3. Making Network Connections Network Connectors and Rear Switch The hub provides 8 dual-speed TP ports. Each can support one con- nection to either a 10BASE-T Ethernet device or a 100BASE-TX Fast Ethernet device using 2-pair UTP cable. One configuration switch is located on the rear panel.
RJ-45 Connectors Each of Port #1 to Port #7 provides one RJ-45 connector, which are implemented as MDI-X jack. An MDI-X jack is designed with internal crossover function. The function allows a connection to a computer using straight-through UTP cable.
Connecting to Computers The RJ-45 connectors labeled 1X to 8X can be used for connecting to the network adapter installed in a computer . The network adapter can be a 10BASE-T adapter, a 100BASE-TX adapter, or a 10/100 dual-speed NW ay adapter .
Connecting to Hubs The following table lists the types and the maximum number of hub connections depending on the configuration switch setting: Configuration T ypes of hubs Connections 10M mode 10BASE.
Connecting to a Fast Ethernet Hub Since the KF-8D is designed to comply with IEEE 802.3u Class II repeater specifications, it can support one connection to another 100BASE-TX Class II hub. The connection rules are: 1. The other hub which is connected to KF-8D must comply with IEEE 802.
4. Interpreting LED Indicators The following figure shows the locations of the LED indicators: Power LED : indicates the status of the repeater power source. State Indication Interpretation On Normal The power of the hub is on. O f f Problem No power is being supplied to the hub.
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 KTI Networks 10BASE-T 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 KTI Networks 10BASE-T - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso KTI Networks 10BASE-T imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul KTI Networks 10BASE-T ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il KTI Networks 10BASE-T, 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 KTI Networks 10BASE-T.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il KTI Networks 10BASE-T. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo KTI Networks 10BASE-T 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.
