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.

At the Summit X650 series switch, connect the 128G connector to the VIM1-SummitStack256 module. At the Summit X480 series switch, connect the 64G connector to the VIM2-SummitStack128 module. The connection process is the same for each connector and the compatible VIM model.

Follow these steps to connect a 128G Connector to a VIM1-SummitStack256 Module, or a 64G Connector to a VIM2-SummitStack128 Module.

  1. Holding the cable connector with the release tab on top, align the connector with the stacking port on the VIM.
