Chapter 2: Virtual Chassis Stacking

10Gbps stack trunks can have both fiber optic transceivers and SP10TW
direct attach cables. The example in Figure 21 illustrates a stack of four
switches located in two separate buildings. SP10TW direct attach cables
connect switches that are in the same wiring closet while fiber optic
transceivers connect the switches across the buildings.
