Ethernet Module Ethernet Module Full-duplex or Auto-negotiate Change speed Auto-negotiate Change duplex Coll 100 Mbps 10 Mbps Half-duplex MDI MDI-X 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).
Example configurations These two example configurations show the combinations of duplex and speed LEDs.
Connecting 100 Mbps hubs with TPE cable 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. Each hub or hub stack is a separate collision domain. Using an Ethernet Module is the only way you can connect Express 10/100 Stackable Hubs to each other with TPE cable while operating at 100 Mbps.
Connecting to a device at full-duplex 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. Connecting to a switch at full-duplex Not all device manufacturers implement auto-negotiation of duplex mode. To ensure the Ethernet Module connects to the device at fullduplex, force the duplex mode to full-duplex. To force the duplex mode, use the Change duplex button: 1 Long press the Change duplex button.
Connecting to a server at full-duplex Ethernet Module Change duplex Auto-negotiate Full-duplex Change speed Half-duplex or Auto-negotiate Coll 100 Mbps 10 Mbps MDI-X MDI 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.
Understanding Ethernet Module LEDs The LEDs on the Ethernet Module provide information about the module’s configuration and status. Ethernet Module Change duplex Auto-negotiate Full-duplex Half-duplex Change speed or Auto-negotiate Coll 100 Mbps 10 Mbps MDI MDI-X The LEDs on both ports light when a cable is attached to either port. Port LEDs The LEDs above a port on the Ethernet Module provide information about the port’s configuration and status.
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). The default duplex mode setting is autonegotiate. LED Status Meaning Auto-negotiate Solid Module is set to auto-negotiate the duplex mode.
NOTE Change speed button and LEDs See the 10BASE-T and 100BASE-TX LEDs on the hub to determine the hub speed. 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. The default speed setting is auto-negotiate.
Fiber Module Fiber Module Auto-negotiate Change duplex Xmt Link Rcv Coll Full-duplex Half-duplex TX RX The Fiber Module acts as a switched port plugged into an Express 10/100 Stackable Hub. The Fiber Module • connects an Express 10/100 Stackable Hub running at 100 Mbps to another hub or other device beyond the 100 meter limitation (up to 160 meters at half-duplex or 2 km at full-duplex).
Connecting to a device at full-duplex Not all device manufacturers implement auto-negotiation of duplex mode. To ensure the Fiber Module connects to the device at fullduplex, force the duplex mode to full-duplex. To force the duplex mode, use the Change duplex button: NOTE A long press is held for 2 seconds or more. A short press is held for less than 2 seconds. 1 Long press the Change duplex button. The Auto-negotiate LED will blink. 2 Short press the Change duplex button.
Connecting to a switch at full-duplex Fiber Module Auto-negotiate Change duplex Xmt Link Full-duplex Half-duplex Rcv TX Coll 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 62.5/125-micron fiber optic cable. The module was forced to full-duplex to ensure a connection to the switch. The maximum cable distances are shown below.
Understanding Fiber Module LEDs The LEDs on the Fiber Module provide information about the module’s configuration and status. Fiber Module Auto-negotiate Change duplex Xmt Link Rcv Coll Full-duplex Half-duplex TX RX 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. LED Status Meaning Auto-negotiate Solid Module is set to auto-negotiate the duplex mode.
Transmit/Receive/Link/Collision LEDs LED Status Meaning Xmt (transmit) Blinking green Port is transmitting data. Off Port is not transmitting data. Blinking green Port is receiving data. Off Port is not receiving data. Solid green Port has a link. Off No link detected. Blinking amber Off Collisions are detected. No collisions are occurring.
