Page 10 - Connection Guidelines; General; Connecting to Devices
8 Connection Guidelines General • Ports on the 220T and 210T hubs are half-duplex. To connect to a device at full-duplex, you must use the optional Ethernet or Fiber Modules. • 220T ports are autonegotiating and can operate at 10Mbps or 100Mbps. The hub matches the highest possible speed of an attac...
Page 11 - Stacking Hubs; Guidelines
9 Stacking Hubs Why Stack? The Express 220T and 210T hubs use the same connectors so they can bestacked together or stacked in combination with the Express 10/100Stackable hub. By stacking Intel hubs you can: • increase the number of available ports, yet still treat the stack as a single repeater. •...
Page 12 - Bridging Segments; Guidelines for bridging a stack of 220T hubs
10 Bridging Segments Bridging 220T Hubs A bridge allows two segments to communicate with each other. Typically, abridge connects segments operating at different speeds, but it can alsoconnect segments operating at the same speed. By default, the Express220T’s internal bridge is active so 10Mbps and ...
Page 13 - Example 3: Bridging with an Ethernet Module
11 Bridging 210T Hubs All ports on the Express 210T hub operate at the same speed (10Mbps or100Mbps) so the hub belongs to only one segment at a time. The 210T hubdoesn’t contain an internal bridge. To communicate, the segments must bebridged by a 220T hub or by an external device (like a 10/100 swi...

15 Can I daisy-chain a 100Mbps hub to the 220T hub with UTPcabling? No. Only hubs operating at 10Mbps can be daisy-chained to the 220T.You must use an Intel Cascade Cable to connect Intel hubs operating at100Mbps. Can I daisy-chain 210T hubs together with UTP cabling? Only if the hubs are operating ...
