To connect a SummitStack 128G cable, follow these steps:
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 (see Connecting a SummitStack 128G Cable).
Firmly press the cable connector into the stacking
port until the spring latch on top of the connector clicks into place.
Repeat the process to connect the other end of the
cable.
