Figure 33. Unsupported Trunk with Only One Link Between Switches
 Trunk links must be the same speed. The example in Figure 34 is
unsupported because the links are different speeds.
Figure 34. Unsupported Trunk with Different Port Speeds

Allied Telesis does not recommend using the AT-XEM2-1CQ Line
Card for a stack trunk because it has only one transceiver port and
the switch has only one expansion port. Refer to Figure 35.
Instead, use two base 40/100Gbps transceiver ports, as shown in
Figure 25 on page 62, to build a 100Gbps trunk.
