We currently have 9 Groovy Epics on the field, it has been a total of 3 times that one board turns on red, and the system keeps running without that I/O, it has happened so far on the serial, on the OVMALP and on the IV24
Failure happens randomly, although I have noticed it somewhat correlates to a cold day after hot days, system is housed inside an office, so temperature change is not so drastic
Field crews always manage to get the system running by removing the board and installing again, or just by wiggling the connection
We always use the provided screw to secure the board, in addition the device is installed inside a filtered ventilated enclosure, but I was wondering if there is some other recommendation besides that, such as dielectric grease on the connection
Regards
