Connecting a SummitStack 128G/64G Stacking Cable
SummitStack 128G/64G cables are used to connect the 128-Gbps stacking ports on Summit X650 series
switches to 64-Gbps stacking ports on Summit X480 series switches.
The 128-Gbps stacking ports are on VIM1-SummitStack256 modules; the 64-Gbps stacking ports are on
VIM2-SummitStack128 modules.
Because of the weight of the SummitStack 128G/64G cable, Extreme Networks strongly recommends
the use of cable management hardware to support the cables and provide strain relief at the
connectors. The following figures show representative types of cable management hardware. Your
particular rack configuration might require other cable management solutions.
