VIM1-SummitStack Versatile Interface Module
The VIM1-SummitStack versatile interface module (Figure 60) provides four cages for installed SFP
optical modules. These ports (numbered 25 through 28) function the same as the front-panel ports. The
VIM1-SummitStack module supports 1000-BASE SFPs. For a complete list of supported SFPs, refer to
the most recent version of the ExtremeEXOS release notes.
The VIM1-SummitStack module also provides two high-performance stacking ports that allow you to
combine multiple units into a single SummitStack management entity. The VIM1-SummitStack module
is the default VIM1 module shipped with the base Summit X650 platform. Ports 23 and 24 of the front
panel are shared with the two rear-panel stacking ports on the VIM1-SummitStack module.
By default, stacking is not enabled, and all 24 front panel ports are available. When stacking is enabled,
you have access to 22 10GBASE ports and 2 stacking ports. For more information about configuring and
operating a SummitStack configuration, refer to the ExtremeXOS Concepts Guide and the ExtremeXOS
Command Reference Guide.
