Stacking with X440 and X480

Stacking with X440 and X480

Hi,
What are the option to stack a X440 and an X480, I belive the X440 can summitstack and summitstack-V (Is there any documentaion on summit stack please).

Does the X440 summitstack-V work with a SFP module and the same with the X480, this would be a SFP module for the summitstack-V?

Does XOS still recognise stacking while usign SFP on X440?

Thanks

The standard SummitStack module allows a 10Gb connection between stack ports and uses the standard stacking cable. The SummitStack-V modules are used for V, V80, V160, V320 stacking. These modules use a QSFP+ connection.

Considering the X440 (Non 10Gb) has SummitStack built-in, you will not be able to stack the X480 with the X440 using the SummitStack-V modules.

I have created a article for this specific question. There is a link attached which has a chart that explains the different models and the respective modules.

Hope this helps!

So the default stacking module in the X440 will work with the stacking module in the X480?

Which stacking module in the X480 will it be? the summitstack-v?

what is the difference between summitstack & summitstack-V?

Thanks

You can stack a 440 with a X480 if there is a summitstack module in the X480. If you have an X440 with 10 Gig SFP+ you could do alternate stacking with these ports to 10 Gig ports on the X480. We do not support stacking on 1 Gig SFP.
