The proprietary high-speed communication protocol that is used over the
stacking links requires multiple twisted pairs and a high level of shielding.
This means that to stack x610 switches, specialized cables and
connections are required.
Modules, Cables, and Connections
VCStack Stacking
The stacks are connected via the stacking ports on the VCStack stacking
modules, which are installed in the back of each switch. There are two
VCStack stacking modules available:
The AT-StackXG, which has two full-duplex, 12 Gbps stacking ports
The AT-x6EM/XS2, which has two 10 Gbps SFP+ stacking slots
The following cables are used to connect the stacking ports when using
