I've the issue since i bought the rack PDU (years ago).
If the unit was new and in warranty I'd advise that you contact support to replace, for now you could try to update to firmware but I'm unsure it will help.
I upgraded AOS and firmware to version 3.9.2 (2016).
Thanks for the suggestion.Let's see how it works in the future, since it loose the LAN connectivity after a blackout.
