CHAPTER2 Ethernet Unit

■Example 2

In this example, many controllers are operated with the HUBs connected in cascade.

*The cascade port, also sometimes called an UPLINK port or MDI port is used when connecting multiple HUBs in cascade. Straight-through cables are used to connect the cascade ports of the HUBs together. However, crossover cables are used when con- necting HUBs not having cascade ports or when making cascade connections without using cascade ports.

*A maximum of 4 HUB units can be connected in cascade.

*The same type network can also be built up by stacking HUBs together using so-called stackable HUBs. In this case, Multiple HUBs connected in a stack are seen as just one large HUB by the network so there is no limit on the number of HUB units that can be stacked.
