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 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).

100BASE-FX Any ports on a single module.
1000BASE-X Up to four Gigabit ports from any switch in the stack, or both
Gigabit ports on two modules installed in a standalone switch.
