NOTE

You must use an Intel Cascade Cable to connect hubs running at 100 Mbps. Do not daisy- chain hubs with TPE crossover cabling.

Intel Cascade Cable

(product code EE110CC)

NOTE

In a managed stack of hubs, the optional Management Mod- ule can communicate with all hubs, regardless of speed.

The Ethernet Module acts as a switch port plugged into a hub. It has the added benefit of connecting to a switch or server configured at full-duplex.

This is the only time you can connect an Express 10/100 Stackable Hub to a device at full-duplex.

Example Configurations

Mixed 10 Mbps and 100 Mbps environment

A stack of Express 10/100 Stackable Hubs can contain hubs running at both 10 and 100 Mbps. However, the hubs running at 10 Mbps and the hubs running at 100 Mbps are on separate network segments. These two segments can’t communicate with each other unless you use another device to bridge them.

There are several ways to bridge the 10 Mbps and 100 Mbps segments:

Use the optional Intel Express Stackable Hub Ethernet Module (product code EE110EM).

Use a switch capable of both 10 Mbps and 100 Mbps operation, such as the Intel Express 10/100 Fast Ethernet Switch (product code ES101TX).

Use a server with two 10/100 adapters installed.

Use the Intel Express 10/100 Downlink (product code EC100DL).

Use a router capable of both 10 Mbps and 100 Mbps operation (not described here).

Bridging with the Intel Express Stackable Hub Ethernet Module (sold separately)

The Ethernet Module plugs into the expansion slot of a 12-port hub running at either 10 Mbps or 100 Mbps. Simply plug the module into a hub running at one speed and connect to a hub running at the other speed, and the Ethernet Module bridges the two collision domains.

If you plug the Ethernet Module into a hub running at 100 Mbps, connect it to a hub running at 10 Mbps with CAT 3, 4, or 5 TPE.

If you plug the Ethernet Module into a hub running at 10 Mbps, connect it to a hub running at

Category 3, 4, or 5 TPE

100 Mbps with CAT 5 TPE.
