Hello,

Currently I have a two different EX3400 virtual chassis stacks.  1st group contains 4 48 port switches and the 2nd group 2 48 ports.  There's a distance of 1000 feet between the stacks with multi mode and single mode fiber available.  What's the best solution to trunk these switch stacks for multiple vlans between them?

You have options.

I think the minimum link speed recommended is 10G for a virtual chassis.  I have done this in buildings with multiple TCs but configured as one virtual chassis.  

In your case, I would set the virtual chassis to pre-provisioned, identify the members and their roles on stack number 1, probably closest to your DMARC .  Zeroize the switches in stack 2. Set vc-ports on the front SFP+ ports and connect fiber between TCs. Give them time to merge.

@Paul Peterson.  I attempted the solution you provided.  However it's failing to recognize the zeroized two switches.  Any idea's?

If you are using the front ports on the switches, you need to set them as vc-ports.

For each port that has fiber connections:

request virtual-chassis set vc-port pic-slot 2 port <> (this would be port 0-3)

To verify:

show virtual-chassis vc-port
