Chapter 5: Building a SummitStack Configuration
Figure 139 shows a stack that combines Summit X670 series switches with Summit X650 and X460 series
switches in a stack of five switches.
The Summit X670 series switches in slots 1 and 2 are connected through their alternate stacking ports
using fiber optic cables. The alternate stacking port on the switch in slot 2 is connected to the Summit
X650 series switch in 3 through the alternate stacking port on an installed VIM1-10G8X module.
The switches in slots 3, 4, and 5 are connected through their native stacking ports. On the Summit X650
series switch, the native stacking port is on the installed VIM1-10G8X module. On the Summit X460
series switches in slots 4 and 5, the native stacking ports are on installed SummitStack modules. From
slot 5, alternate stack port 2 on the Summit X460 series switch is connected to alternate stack port 1 on
the Summit X670 series switch in slot 1.
