VCStack Stacking Module
A Virtual Chassis Stack (VCStack) is two or more separate Allied Telesis
switches that are configured to operate as a single logical switch. The
component switches are connected via VCStack stacking modules
installed in each switch.
Two VCStack stacking modules are available:
The AT-StackXG has two full-duplex, 12 Gbps stacking ports, shown in
Figure 30.
The AT-x6EM/XS2 has two 10 Gbps SFP+ stacking slots, shown in
Figure 31. Note that the port speed of the AT-x6EM/XS2 is fixed at
10 Gbps.
