Summary of Conditions for Alternate Stacking Ports
Alternate stacking ports must be 10-Gbps Ethernet ports. In addition, specific switch models have the
requirements listed in this section.
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 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 a VIM2-10G4X module. Ports S3 (51)
and S4 (52) can then be configured as alternate stacking ports.
●
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.
●
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.

module to configure alternate stacking ports.
