MAKING

CONNECTIONS

This chapter discusses how to make connections to the hub’s twisted-pair ports, cascading hubs to create a stack, and linking with other hubs (or hub stacks).

Hub Cascading/Building a Stack

You can stack up to five hubs using the daisy-chain ports to form one logi- cal hub. In this configuration, the interconnected hubs constitute a single logical unit, providing a maximum of 40 twisted-pair ports.

Use the provided daisy-chain cable to connect the Daisy-Chain OUT port on the rear panel of one hub to the Daisy-Chain IN port on the hub below it, as shown in the figure below. Repeat this procedure for each hub to be included in the stack.
