4 Ethernet Module The Ethernet Module acts as a switch port plugged into an Express 10/100 Stackable Hub. The Ethernet Module • bridges Express 10/100 Stackable Hubs running at 10 Mbps to hubs running at 100 Mbps. • connects Express10/100 Stackable Hubs running at 100 Mbps to each other with TPE cable (creating separate collisions domains).
5 Example configurations These two example configurations show the combinations of duplex and speed LEDs. Bridging hubs running at 100 Mbps to hubs at 10 Mbps This Ethernet Module is plugged into a hub running at 100 Mbps. The module is then connected to a 10 Mbps hub by CAT 3, 4, or 5 TPE cable.
6 Connecting 100 Mbps hubs with TPE cab le Class I hubs, such as the Intel Express 10/100 Stackable Hub, cannot be directly connected with TPE cable when running at 100 Mbps. However, since the Ethernet Module acts as a switched port on a hub, you can use it to connect to another 100 Mbps hub with TPE cable.
7 NOTE A long press is held for 2 seconds or more. A short press is held for less than 2 seconds. Connecting to a de vice at full-duple x Express 10/100 Stackable Hubs operate at half-duplex. The only way to connect to a device at full-duplex is with an Ethernet Module.
8 Connecting to a server at full-duplex This is an Ethernet Module plugged into a hub running at 10 or 100 Mbps. The module is then connected to a server with an Intel EtherExpress™ PRO/100 LAN Adapter using CAT 5 TPE cable. Use the MDI-X connector on the Ethernet Module.
9 Under standing Ethernet Module LEDs The LEDs on the Ethernet Module provide information about the module’s configuration and status. Port LEDs The LEDs above a port on the Ethernet Module provide information about the port’s configuration and status.
10 Change duplex button and LEDs You can determine the Ethernet Module’s duplex configuration and status from the duplex LEDs. Use the Change duplex button to cycle among duplex modes. Attach any Express 10/100 Stackable Hub to the Ethernet Module and the module will automatically negotiate the correct duplex setting (always half-duplex).
11 Change speed button and LEDs You can determine the speed of the connection between the Ethernet Module and device from the speed LEDs. Use the Change speed button to cycle among speed settings. Attach any Express 10/100 Stackable Hub to the Ethernet Module and the module will automatically negotiate the correct speed.
12 NOTE At half-duplex, you can con- nect hubs up to 160 meters apart. At full-duplex, you can con- nect hubs up to 2 km apart. Fiber Module The Fiber Module acts as a switched port plugged into an Express 10/100 Stackable Hub.
13 NOTE A long press is held for 2 seconds or more. A short press is held for less than 2 seconds. Connecting to a de vice at full-duple x Not all device manufacturers implement auto-negotiation of duplex mode. To ensure the Fiber Module connects to the device at full- duplex, force the duplex mode to full-duplex.
14 Connecting to a switch at full-duplex Fiber Module Auto-negotiate Full-duplex Half-duplex Change duplex Xmt Link Rcv Coll TX RX This is a Fiber Module plugged into a hub running at either 10 or 100 Mbps. The module is then connected to an Intel Express 10/100 Fast Ethernet Switch at full-duplex using 62.
15 Under standing Fiber Module LEDs The LEDs on the Fiber Module provide information about the module’s configuration and status. Duplex LEDs You can determine the Fiber Module’s duplex configuration and status from the duplex LEDs. Use the Change duplex button to cycle among duplex modes.
16 Transmit/Receive/Link/Collision LEDs LED Status Meaning Xmt (transmit) Blinking green Port is transmitting data. Off Port is not transmitting data. Rcv (receive) Blinking green Port is receiving data. Off Port is not receiving data. Link Solid green Port has a link.

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 Intel EE110EM 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 Intel EE110EM - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Intel EE110EM imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Intel EE110EM ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Intel EE110EM, 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 Intel EE110EM.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Intel EE110EM. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Intel EE110EM 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.
