Versatile Interface Modules for the Summit X650
Series Switches
The back panel of the Summit X650 series switch has a replaceable VIM1 or VIM3 versatile interface
module. These modules provide dedicated high-speed stacking ports or Ethernet ports. For more
information about using the stacking ports, see Chapter 5.
The following VIMs are available for the Summit X650 series switches:
● VIM1-10G8X module (this page)
● VIM1-SummitStack module (page 164
● VIM1-SummitStack512 module (page 164)
● VIM1-SummitStack256 module (page 165)
● VIM3-40G4X module (page 165)
VIM1-10G8X Versatile Interface Module
The VIM1-10G8X versatile interface module (Figure 120) provides eight cages for installed SFP or SFP+
optical modules. In addition, the VIM1-10G8X module is compatible with the SFP+ direct-attach passive
copper cable. For information about the supported optical modules, refer to the most recent version of
the ExtremeXOS Hardware and Software Compatibility Matrix.
The VIM1-10G8X module also provides two high-performance stacking ports that allow you to combine
multiple units into a single SummitStack management entity. The stacking ports on the VIM1-10G8X
module are not shared with the front panel ports.
Ports 31 and 32 on the VIM1-10G8X module can be configured as alternate stacking ports in a
SummitStack configuration that uses the SummitStack-V feature. For more information about stacking
Summit family switches, see Chapter 5.
