jdp sb10q Fair comment, we are using two 12V, 5A adaptors (XP Power AFM60US12C2) plugged into front and rear of kasli but I will swap over to an external bench top PSU with more current incase that is the issue.
jdp sb10q Tried an external benchtop PSU - current draw was only a few A at 12V, no change in behaviour
rowanq @jdp did you ever resolve this issue? We are occasionally getting the "aux packet error (timeout)" error, accompanied by all DAC and TTL channels going to 0V.
jdp rowanq apologies I missed the notification on this - we replaced with copper SFP connectors rather than fiber cables and this seemed to solve the problem. I can dig out the part number if you would find it useful
