Why Stack?

The Express 220T and 210T hubs use the same connectors so they can be stacked together or stacked in combination with the Express 10/100 Stackable hub. By stacking Intel hubs you can:

•increase the number of available ports, yet still treat the stack as a single repeater.

•use a single Management Module to manage all hubs in the stack.

•use the 220T’s internal bridge so 10Mbps and 100Mbps segments can communicate.

Connect the Cacade Cables to the hubs as shown in the diagram.

Guidelines

•You must use an Intel Cascade Cable to stack the hubs. Do not daisy- chain hubs operating at 100Mbps with UTP cable.

•A stack can consist of any combination of 220T, 210T, or Express 10/100 hubs (12- or 24-port versions).

•You can stack up to eight hubs.

•When cabled correctly, the top hub in a stack is numbered hub 1.

•If there is more than one 220T hub in a stack, only one bridge is active at a time. The lowest numbered 220T hub is the active bridge.

•All devices at the same speed are in the same segment. For example, all devices at 10Mbps are in one segment and all devices at 100Mbps are in another.
