Connecting Hubs Together

Twisted-Pair Cascade Connections

To expand your network, the hub can be connected to other hubs with straight-through cable by using the Media Dependent Interface (MDI) switch.

MDI/MDI-X switch

The MDI/MDI-X switch controls how the signals are sent through the twisted- pair cable connected to Port 16. The hub is shipped with the switch in the MDI- X position. The switch has two positions:

■In the MDI position, use Port 16 to connect your hub to another hub. In this position, the hub reverses the Tx and Rx port pairs for you. This allows you to use “straight-through” cable rather than “cross-over” cable to connect two hubs together. The cable can be up to 100 meters in length.

■In the MDI-X position, use Port 16 to connect your hub to a PC or similar device using “straight-through” cable.
