Connecting a SummitStack 64G/20G Stacking Cable
SummitStack 64G/20G cables are used to connect the 64-Gbps stacking ports on Summit X480 series
switches to 20-Gbps stacking ports on Summit X480 series, Summit X650 series, or other Summit series
switches. The 64-Gbps ports are on VIM2-SummitStack128 modules in Summit X480 series switches.
The 20-Gbps ports are on one of the following:
● VIM1-10G8X module installed in a Summit X650 series switch
● VIM1-SummitStack module in a Summit X650 series switch
● VIM2-SummitStack module in a Summit X480 series switch
● Rear panel of Summit X250e, X450, X450a, or X450e series switches.
To connect a SummitStack 64G/20G cable:
1 Connect the 64-Gbps connector to the VIM2 module as follows:
a Holding the cable connector with the release tab on top, align the connector with the stacking
port on the VIM2 module in the Summit X480 series switch (Figure 89).
