Connecting Hubs Together

Twisted-Pair Cascade Connections

To expand your network, the hub can be connected to other hubs by using

the Media Dependent Interface (MDI) switch.

The MDI/MDI-X switch controls how the signals are sent through the twisted-

pair cable connected to Port 1. The hub is shipped with the switch in the

MDI-X position. The switch is a pushbutton switch with

two positions:

In the MDI position, use Port 1 to connect your hub to another

hub. In this position, the hub reverses the Tx and Rx port pins for

you. This allows you to use “straight-through” cable rather than

“cross-over” cable to connect two hubs together.

In the MDI-X position, use Port 1 to connect your hub to a PC or

similar device using “straight-through” cable. In the MDI-X position,

the switch is exposed by 0.10 inches (2.5 mm) in front of the bezel.

Caution

You must disconnect the device connected to Port 1 before changing the

position of this switch. If you push the MDI/MDI-X switch and change

its position while your network is running, the hub or PC connected to

Port 1 will be disrupted. To restore your connection, push the

MDI/MDI-X switch in again.
