Karan, thanks much for sharing your expertise with me.
I'm running RE-S-1800x4, MPC-3D-16XGE-SFPP and DPCE-R-40GE-SFP in my kit. I doubt the DPCE-R-40GE-SFP can work with 16.1. If possible, I would rather stay on 15.1R6.7 if possible, although if not possible, I am willing to consider options.
Thanks.
