The RJ-45 ports used for one side of a trunk must all be on the
same internal switch chip. The port groups permitted include:
Switch Model
SMC6912
SMC6924
The 100BASE-FX fiber ports used for one side of a trunk must all
be on the same module. However, the 1000BASE-SX 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.
Media Module
100BASE-FX
1000BASE-SX
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).
Group 1

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