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 "...
Thanks StephenB :
Not sure why you say that it's normal for a NAS to remain powered off when power is restored. I quoted Netgear's website directly, repeating it here:
"When wake-on-LAN is enabled, if the unit is disconnected from AC power it will power on when AC power is reconnected."
This is why I mentioned WoL. The sentence reads "Enable WoL, your unit will auto-power on after a power outage", doesn't it? I understand the main use for WoL using magic packets - this sentence indicates that WoL has a dual-purpose. Either that, or Netgear's website is incorrect or misleading.
Also, to be clear (which I wasn't), although the RN528X did not power on after power was restored, the RN314 and RN424 did. The RN212 did not power back on. So the result was inconsistent, I guess you could say. I wanted to be clear that WoL was enabled on all of them.
Re: "odd that the RN528 powered down, but the other NAS's did not" - I didn't provide enough info. They all powered down, which they had to because the UPS was completely exhausted after less than 20 minutes. The outage was several hours long. What I was trying to say was, I was half way across the country when this happened. When power was restored and two of the NAS's came back on, they began frequent barking about no connection to the RN528 UPS master. Generated a lot of annoying notifications that wouldn't have happened if the RN528 powered back on as it should have (well, at least if I'm reading the Netgear sentence correctly).
"When wake-on-LAN is enabled, if the unit is disconnected from AC power it will power on when AC power is reconnected."
I'm thinking you mean here:
FWIW, that screenshot doesn't match the web ui. Note the OS-6 manual says nothing about AC power in the WoL section (see page 229):
And the KB article is incorrect - the WoL setting doesn't affect the power behavior.
JulienR - This article needs revision.
I'm interested in how I could, if desired, have all 4 ReadyNAS boxes power back on after power is restored, using a WoL magic packet. None of my PC's power back on after an outage but I do have a Lenovo T490 laptop that is running only Home Assistant OS, consuming 7W. That laptop is AC powered so in an outage, the laptop will run for 6-7 hours before dying. Wondering if that laptop could be used to deliver WoL magic packets to each of the ReadyNAS units, after some delay to allow for all the switches/controller to re-establish the network.
This could be done - There is at least one python module that could be used.

It is possible to send the packet as a broadcast packet, in which case a single WoL packet would wake up all WoL devices that receive it.
One caveat - the T490 might need to be connected with ethernet in order for the packets to be forwarded to the NAS. Particularly if you use a broadcast packet.
If the NAS is on an UPS and detects that the UPS is on battery power, it will initiate a shut-down. That reduces the load on the UPS battery, which may last until power is restored. In that case, the NAS never sees a power loss and restore, and does not come back on.
Yes. If you only have the NAS and the ethernet switch connected to the UPS, then the load drops substantially when the NAS shut down. The remaining battery power in the UPS can keep the the switch running for long time (and power continues to be delivered to the NAS, though they use almost nothing after the shutdown).
Though this also should apply to the other two NAS (assuming they were also connected to the same UPS, and that the network path was also connected to that UPS).
A safe way to test your new configuration is to temporarily shift all the UPS devices to normal (unprotected) power, and instead put a different load on the UPS. Leave the USB connections in place, and then pull the main power going to the UPS. When the UPS battery drains, the units should all shut down normally. And if that fails for some reason, the NAS will just keep running (since the power was never interrupted).
