I have two EX4300 switchs in a stack. When I first got them I had them lincked usinging optic calbles, they are now using the standard stackign cabels, and only xe-0/2/2-3 & 1/2/2-3 are configured. So I was suporsed to see the error below shoing a failed connnecion:

The slots look fine

I also confirmed that the ports wer no longer used as vc-ports and were unconfigured.

I am open to any additional guidance on where to look next for the source of these errors.
