SMC Networks 1000BASE-X Manual De Usuario

3-53

The MT-RJ ports used for one side of a trunk must all be on the same 
internal switch chip. The port groups permitted include:

The 100BASE-FX SC-type fiber ports used for one side of a trunk must all 
be on the same module. However, the 1000BASE-X ports used for one 
side of a trunk may be on any switch in the stack, or both on the same 
switch if used standalone. 

For example, when using Gigabit ports to form a trunk within a stack, the 
Gigabit ports will all be at Port 25. In this case, you could specify a trunk 
group consisting of:
(Unit1-Port25, Unit2-Port25, Unit3-Port25, Unit4-Port25), 
or two trunks consisting of:
(Unit1-Port25, Unit2-Port25) and (Unit3-Port25, Unit4-Port25).
