Figure 24: Unsupported Trunk With Both Direct Connect And Fiber Optic Cables On Xem2-12Xt Line Cards - Allied Telesis SwitchBlade x908 GEN2 Installation Manual

 The XEM2-12XS Line Card supports 10Gbps 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 XEM2-12XS
Line Cards in Figure 24 is unsupported because it uses both types
of cables.
