Power outage - RN528X does not auto-power on, causing UPS Slave errors
Early southern California winter storm, lost power for a few hours. Have the following setup: Cyberpower CP1500PFCLCDA 1500VA UPS RN528X is USB-connected to UPS and configured in RN OS 6.10.9 "...

That is normal (assuming the UPS battery drained).
That is also normal behavior with your RN424, RN314, and RN212.

Can you explain what WoL has to do with this?
WoL allows you to power up the NAS over the network by sending a "magic" packet to the NAS. Is something on your network doing this? Note it doesn't mean that the NAS will power up when it detects ethernet.

No, but it is rather odd that the RN528 powered down, but the other NAS did not. Are all the NAS (and the network equipment between them) all connected to this UPS?
