C3650 stacking question

[smailmilak]

Hi,

If I buy two C3650 and want to stack them, do I need two stacking kits?

I see that in the kit the following parts are included:

Cisco Catalyst 3650 Stack Module x2

STACK-T2-50CM x1

One kit should be enough?

I think you are right, to make the stack you need an adapter for each switch so it's seems the upgrade kit is enough.

I think that it's better to connect the switch using two cables to have a loop and avoid a failure will broke the stack but I think it could work also with just a cable

Bye,

Hi;

It’s always recommended to connect 2 x switches via 2 stack cables, but Stack can work on single cable.

In case if your switches connect with 2 x stack cable and one of the stack port is flapping and causing instability in the stack ring or disable the stack port, then the stack will operates at half bandwidth.

Thanks & Best regards;

Thanks both of you. 

I will go with two stack kits so I can create a loop in case of a failure.
