Fibre connected switch be a stack member?

[paul.thomas]

I have a number of 3750 Switches, one will be in a location 400m away connected via fibre through GBIC modules. Can this be a stack member or does it have to be a seperate stack with its own IP address?

Hi Paul,

The longest stack cable is 3 meters long, so you cannot stack the switch 400m away and you need to put it as standalone or separate stack:

Kind Regards,

Not possible.

The method of "stacking" two switches together at that distance is VSS.  And currently, only the Sup720 and Sup2T will support VSS.  Very soon the 4500R+E Sup7E and Sup7LE and the 4500X will support VSS.

And that's about it.
