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.
