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).

•connects an Express10/100 Stackable Hub to another device at full-duplex, such as a server or switch.

Bridging 10 and 100 Mbps hubs

To bridge hubs of different speeds, simply plug an Ethernet Module into an expansion slot on a 12-port hub (see “Quick Start” on page 1), then connect to a hub running at the other speed. The Ethernet Module bridges the two collision domains.
