The stacking-support option is enabled by default for X450-G2 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 X450-G2 switches. For more information, see Selecting Native and Alternate Stacking Ports.
Stacking Method | Speed per Link (HDX) | Cable Type and Lengths |
---|---|---|
SummitStack-V84 Uses rear panel dedicated 21 Gb stacking ports Available only in stacks of X450-G2 switches running the same version of ExtremeXOS | 21 Gbps | 0.5m, 1.0m, 3.0m. 5.0m QSFP+ passive copper cable |
SummitStack-V (Front panel 10G models) | 10 Gbps | 0.5m–40km SFP+ |
For native stacking with the X450-G2 switch, use the two fixed 21 Gb QSFP+ stacking ports on the rear of the switch, as shown in X450-G2 Switch: Native Stacking Ports. These stacking ports provide SummitStack-V84 stacking and can be stacked natively only with other X450-G2 switches.
SummitStack-V84 connections require direct-connect QSFP+ copper cables.
The X450-G2 is the only Extreme Networks switch that supports SummitStack-V84.
1 = 21 Gb QSFP+ stacking ports | 2 = Grounding lug |
Alternate stacking (SummitStack-V) is supported for the X450-G2 10GE4 switch models, as summarized in Alternate Stacking Ports for X450-G2 Switches. Use the front-panel 10G ports for alternate stacking.
