Figure 21. Invalid 10Gbps Trunk of Only One Link



As mentioned earlier, a 10Gbps trunk can have either fiber optic
transceivers or AT-SP10TW direct attach twinax cables. However,
a trunk cannot have both types of cables. An example of this type
of invalid trunk is shown in Figure 22.

Figure 22. Invalid 10Gbps Trunk with Both Fiber Optic Transceivers and

AT-SP10TW Direct Attach Cable



The links of a stack trunk must all be the same speed. Thus, a
stack trunk cannot have both 10Gbps links and 40Gbps or
100Gbps links. Figure 23 is an example of an invalid trunk with
links of different speeds.
