Module
Using SummitStack-V160 Stacking
A stacking rate of 160 Gbps can be achieved using certain configurations of Summit switches. For
example, a Summit X670V (X670V-48x or X670V-48t) switch can be connected to a Summit X650
series switch through 40-Gbps stacking connections that provide 160 Gbps full duplex bandwidth. This
connection is performed using the VIM4-40G4X module in the Summit X670V switch and the
VIM3-40G4X module in the Summit X650 series switch. V-160 stacking is also supported on the X480
series switch using the VIM3-40G4x module, and on the X770 using the QSFP+ ports.
On the VIM4-40G4X module, ports S3 and S4 are the stacking ports.
The following figure shows an example stack using Summit X670, X650, X480, and X460 series
switches.
