New Octo GX, updated to firmware 2.60, with 7 new smart shunts connected with ve.direct cables.
The "lower" 6 ve.direct ports work fine, the upper 4 do not. We've got 7 smart shunts - swapping cables around between different shunts and different ve.direct ports has confirmed no shunts work on the "upper" 4 ports, but they do work on the lower. Suspecting it's a hardware problem but wanted to see if it's a known thing since it seems coincidental the working ports are all on the same side. Restarting with different ports in use hasn't made a difference.
