Summit X450a and X450e series switches:
To use the SummitStack-V feature, you must install one of the following port option cards to add 10-
Gbps ports to the switch.
•
XGM2-2xf option card
•
XGM2-2xn option card
•
XGM2-2sf option card
•
XGM2-2bt option card
Summit X460 Series Switches:
To use the SummitStack-V feature, you must install an XGM3-2sf, XGM3S-2sf, or XGM3S-2xf port
option card to add 10-Gbps ports to the switch.
Summit X480 series switches:
•
Summit X480-48t and X480-48x switches do not have 10-Gbps ports on the base model switch. To
use the SummitStack-V feature on these switches, you must install either a VIM2-10G4X module
(ports S3 (51) and S4 (52) can then be configured as alternate stacking ports). Alternate stacking
ports are not supported with the VIM3-40G4X.
•
On a Summit X480-24x with an installed VIM2-10G4X module, you can configure ports S3 (29) and
S4 (30) as alternate stacking ports for the SummitStack-V feature. If you use a VIM3-40G4X module
for stacking, ports 25 and 26 are configured as the alternate stacking ports.
•
On a Summit X480-24x switch with no installed VIM2 module, you can configure ports 25 and 26 on
the switch front panel as alternate stacking ports.
•
On a Summit X480-24x switch with installed native stacking ports on a VIM2 module, you can do
either of the following:
•
Configure both ports 25 and 26 on the switch front panel as alternate stacking ports.
•
Configure one alternate stacking port on the switch front panel and use a native stacking port on
the installed VIM2 module.
Summit X650 series switches:
•
Summit X650 series switches must always have an installed VIM1 or VIM3 module.
•
If a VIM1-SummitStack or VIM1-SummitStack256 module is installed, ports 23 and 24 on the switch
front panel can be configured as alternate stacking ports.
•
If a VIM1-10G8X module is installed, ports 31 and 32 on the VIM1-10G8X module can be configured as
alternate stacking ports.
•
If a VIM3-40G4X module is installed, ports 23 and 24 can be configured as the alternate stacking
ports.
Summit X670 series switches:
When ports 47 and 48 are used as alternate stacking ports, ports 45 and 46 are not available to use as
data ports.
Summit X770 series switches:
When ports 103 and 104 are used as alternate stacking ports, ports 101 and 102 remain available to use
as data ports.
