Hello,

this night my SMT750RMI2U reported the "AVR Relay Weld" error but I'm not able to check if there was an over/under voltage that caused it.

I unplugged it and removed all the clients connected, powered on again and made a self-test from diagnostic menu: everything is ok.

Now I'm wondering if that error could be caused by the heat inside the rack, the temperature is always under control by automatic fans if his maximum is 39 °C.

Thank you.
