Modular DR5 random power reset

[rendersman]

Hi all.. We have a Modular DR5 that about every six months does a random restart.. Could happen at anytime, system doesn't seem extraordinarily busy, system is on APC ups at 30% load. I put it on the ups trying to prevent this issue but still does it..

Any thoughts?

is it just the surge protector or do you have other lightning protection ?

Ive run into this with Panamax towermax and a ups .

No lightning or surge suppression.. Just the UPS. No storm activity when it restarts, seems to be random..
