2. Firmly press the cable connector into the stacking port until the spring latch on top of the connector
clicks into place.
Connecting a SummitStack 64G Stacking Cable
SummitStack 64G cables are used to connect the 64-Gbps stacking ports on the VIM2-SummitStack128
module in Summit X480 series switches.
Because of the weight of the SummitStack 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 may require other cable management solutions.
