 Main device for stack.


 Total members:1


 Management-vlan:1(default vlan)

The first device does not see the second. I can create a cluster, but a stack - no.

 This device is not in stacking.

I don't understand:

- Do I wrong operations?

- Or my devices or my cable not for stacking?

Excuse me! Error!

Not optic orabge cable but optic orange cable.

Or this cable not for stack?

The special cable is necessary?
