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.
C a u t i o n
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.
