Using Summitstack-V160 Stacking - Extreme Networks Summit X150 Series Hardware Installation Manual

Using SummitStack-V160 Stacking

A Summit X670V-48x switch can be connected to a Summit X650 series switch through 40-Gbps stacking
connections that provide 160 Gbps full duplex bandwidth. This is done using the VIM4-40G4X module
in the Summit X670V-48x switch and the VIM3-40G4X module in the Summit X650 series switch.
On the VIM4-40G4X module, ports S3 and S4 are the stacking ports.
Figure 135 shows a stack using Summit X670, X650, X480, and X460 series switches.

To connect a VIM3-40G4X or VIM4-40G4X stacking port to a stacking port on a VIM2-SummitStack-V80
or SummitStack-V80 module, you must set the VIM3 or VIM4 port to operate at the slower speed of the
SummitStack-V80 port. To do so, use the
command. For more information about configuring stacking ports, see the ExtremeXOS Concepts Guide.
