Building a SummitStack Configuration
Summit Family Switches Hardware Installation Guide

Combining Different Types of Stacking Ports
Using special conversion cables, you can build a SummitStack configuration that combines 40-Gbps
stacking connections with 256-Gbps connections or with 128-Gbps connections.
Figure 111
shows a
sample configuration using the following switches:
●
Summit X650 series switches with installed VIM1-SummitStack256 modules
●
Summit X450a series switch with integrated SummitStack ports
●
Summit X480 series switch with installed VIM2-SummitStack module
Figure 111: Combining Stacking Port Types—A
The following cables are used to make the stacking connections:
●
SummitStack 128G cable between the two Summit X650 series switches at the top (slot 1 and slot 2)
●
SummitStack 128G/20G stacking cable between the Summit X650 series switch and the Summit X480
series switch (between slot 2 and slot 3)
●
SummitStack 20G stacking cable between the Summit X480 series switch and the Summit X450a
series switch (between slot 3 and slot 4)
●
SummitStack 128G/20G stacking cable between the Summit X450a series switch and the Summit
X650 series switch (between slot 4 and slot 1)
Table 56
lists the recommended order for connecting the stacking ports in this example.
