Using the SummitStack-V80 Stacking Module or
VIM2-SummitStack-V80 Module
The SummitStack-V80 stacking module and VIM2-SummitStack-V80 module allow you to use active or
passive direct-attach QSFP+ cables to connect stack members across rows in a data center. In Figure 113,
passive copper cables are used to connect adjacent switches in the same rack, and the active fiber cables
provide connections up to 100 meters long between racks. The illustration shows Summit X460 series
switches; Summit X480 series switches could be used in the same way.
