Stacking Hubs 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. 1 2 3 4 5 6 7 8 9 10 11 12 Left (Orange/Green) Orange = 10Mbps Green = 100Mbps Solid = Link Blink = Activity Class I Right (Yellow) Solid = Disabled Blink = Wrong speed Intel Express 220T Stackable Hub Colls 10Mbps Colls 100Mbps RPS Bridged Managed Status Power Enable/Disable Bridging Express 220T Hub + Guidelines Intel Cascade Cable Can stack with 1 2 3 4 5 6 7 8 9 10 11 12 Left (Green) Solid = Link Blink = Activity Class I Right (Yellow) Solid = Disabled Blink = Wrong speed Intel Express 210T Stackable Hub Change Hub Speed 10Base-T 100Base-TX Collision Managed Status Power 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Intel Express 10/100 Stackable Hub Change Hub Speed 10Base-T 100Base-TX Collision Managed Status Power 17 18 19 20 21 22 23 24 Left (Green) Solid = Link Blink = Activity Class I Right (Amber) Solid = Disabled Blink = Wrong speed Express 210T Stackable Hub and Express 10/100 Stackable Hub (12- or 24-port versions). • You must use an Intel Cascade Cable to stack the hubs. Do not daisychain 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. Connect the Cacade Cables to the hubs as shown in the diagram.
