Using the VIM1-SummitStack512 Module
The VIM1-SummitStack512 versatile interface module allows you to connect two Summit X650 series
switches in a cross-over or back-to-back configuration, using SummitStack 128G cables (
Figure 115
). This
configuration provides two bidirectional links operating at 256 Gbps between the two switches.
Figure 115: Stacking Connections Using VIM1-SummitStack512 Modules
and SummitStack 128G Cables
Unlike other stacking configurations, with the VIM1-SummitStack512 modules, ports are connected in
pairs of matching port numbers. When you connect stacking cables to installed VIM1-SummitStack512
modules, match the stacking ports as listed in
Table 59
.
