Intel EE110EM manual Connecting 100 Mbps hubs with TPE cable

NOTE

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 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.

Category 5 TPE (100 meters max.)

Because you’re connecting to a hub port, you cannot establish a full- duplex connection between the hubs.

You don’t need to configure the speed or duplex mode of the Ethernet Module. Auto-negotiation will work for both settings.

Notes on connecting hubs running at 100 Mbps

1Use only Intel Cascade Cable (product code EE110CC) to stack hubs.

2Never connect hubs operating at 100 Mbps with TPE cable unless you use an Ethernet Module.

3No configuration of the speed or duplex mode is needed.

4Do not change the duplex mode to full-duplex.
