Not a Problem AXZEZ Support Team, well your replies were much quicker than other forums that I approached for help in the past..... so kudos to you and your team.... 1. Yes, thanks for the explanation around the single line availability from CM4. I am interested in the redundancy part as I want to use it as NAS device. Any help on converting all ports to WAN would be of great help. 2. Will give it a shot and let you know the results. Already spent many hours on re-compiling the kernel with negative results, tried both local and cross compilation using rpi documentation. I do understand that provide a detailed documentation while building a product at such rapid pace is difficult. 3. If i am not going to use the 3 LAN ports as LAN, do i really need the swconfig deb package to patch the kernel or just the new kernel patch is sufficient. 4. All the 3 Models you have in store are same as mine in dimensions, which are standard sizes of a PSU. I was looking for an option similar to the RPI CM4 IO Board 12v Barrel connectivity instead of ATX connector. 5. Thanks for the confirmation.
