Connecting a SummitStack 128G/20G Stacking Cable

SummitStack 128G/20G cables are used to connect the 128-Gbps stacking ports on Summit X650 series switches to 20-Gbps stacking ports on Summit X650 series or other Summit series switches.

The 128-Gbps ports are on VIM1-SummitStack256 modules in Summit X650 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 128G/20G cable, follow these steps:

  1. Connect the 128-Gbps connector to the VIM1-SummitStack256 module as follows:
    1. Holding the cable connector with the release tab on top, align the connector with the stacking port on the VIM1 module in the Summit X650 series switch.

    2. Firmly press the cable connector into the stacking port until the spring latch on top of the connector clicks into place.
  2. Connect the 20G connector as follows:
    1. Align the cable connector with the stacking port connector on the rear of the switch (see Connecting the 20G Connector).
    2. Firmly press the cable connector into place on the mating stacking port connector.
    3. Align and tighten the retaining screws on the cable connector.
