The answer is: check the cabling. When its dark in the cabinet and you're rearranging DACs from one layout to another something is bound to get plugged in wrong.
The steady blinking seems to be a feature of the QFX5100-48T. Any active port configured as a VCP seems to be doing it. The VCPs on the 24Q blink according to traffic levels.

This seems to be wired up according to Juniper's Virtual Chassis recommendations so what did I miss?
