How to stack 3 ERS 3626 Switches

[usman869]

I have 3 ERS3626 switches How can I stack them ?

Great question.  The documents are not explicit.  

if you look at the factsheets see page 5.  3M, 5M and 10M 10GBASE-CX DACs are also supported as stacking cables on ERS 3600.

That can be interpenetrated for me that you can use SFP+'s or DACs.  But that is not a guarantee

Do you have the ability to test this yourself? Do yo have two ERS3600s and SFP+ optics on hand?

Hi Paul:

 Thank your update.  It was verified through 10GGbic + fiber patch cable substituted of DAC under stacking mode. It is not workable. The status of interface ( port27) was "unsp"(maybe unsupported I guess).

Follow the instructions here.

You will need stacking cables.   See page 7

But to the best of my knowledge they are just 10GE SPF+ DAC cables.

Is it a must to order 10Ge SPF+ DAC cables? It could  be replaced by 10GBic + fiber cable or not.
