Figure 17: Invalid Trunk Using Both Direct Connect And Fiber Optic Cables On At-Xem2-12Xt Line Cards - Allied Telesis AT-SB*908 GEN2 Installation Manual

Chapter 2: Virtual Chassis Stacking
 The AT-XEM2-12XS Line Card supports 10Gbps AT-SP10TW
direct connect twinax cables in addition to fiber optic transceivers.
You can use direct connect cables for trunk links when switches
are physically close together, such as in the same equipment rack
or adjacent racks. However, you cannot build a trunk with both
direct connect cables and fiber optic transceivers. A trunk can have
either one or the other, but not both. The example trunk of AT-
XEM2-12XS Line Cards in Figure 17 is invalid because it uses
both types of cables.
