Summit X460 Stacking

The stacking-support option is disabled by default for Summit X460 switches. For more information, see Enabling and Disabling the Stacking-Support Option.

The stacking port selection option, which allows you to choose between native and alternate ports, is enabled by default for X460 switches. For more information, see Selecting Native and Alternate Stacking Ports.

Stacking Methods for X460 Switches

For X460 native stacking, install a VIM2-SummitStack or VIM2-SummitStack-V80 port option card into the rear of the switch.

The VIM2-SummitStack port option card requires standard SummitStack cables.

VIM2-SummitStack Port Option Card

The VIM2-SummitStack-V80 port option card uses 40G QSFP+ cables to make the stacking port connections.

VIM2-SummitStack-V80 Port Option Card

For a complete listing of compatible cables and optical transceivers, see the Extreme Hardware/Software Compatibility and Recommendation Matrices.

To use alternate stacking on a Summit X460 switch, you must install an XGM3-2sf, XGM3S-2sf, or XGM3S-2xf port option card to add 10-Gbps ports to the switch. Alternate Stacking Ports for X460 Switches shows which port option cards are compatible with each X460 switch model for alternate stacking.
