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 "...
However, after power was restored, RN528X did not power back on. It remained powered down.
That is normal (assuming the UPS battery drained).
That is also normal behavior with your RN424, RN314, and RN212. After they properly shut down, you need to manually power them up again.
and all with WoL enabled.
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.
Am I doing something wrong by using one NAS as the "Host" for UPS and the others as "Slaves"?
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 powered by this UPS?
Think I may have found the answer to what happened... Sandshark posted this in an old 2021 thread:
There is still a scenario in which this doesn't help, though. 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.
Two NAS units were powered on at the time of the power outage - presumably both were gracefully shut down by the UPS (RN528 via USB connection to UPS and RN212 via Remote UPS Slave to RN528). Per the above, these two units would not automatically power back on, and in fact, they didn't. The other two units were powered off at the time of the AC power outage (RN424 and RN314), and both of these did turn on automatically when power was restored. This makes sense now.
With this in mind, I reconfigured the UPS as follows:
- All 4 ReadyNAS boxes have UPS settings configured as SNMP UPS
- The UGreen DXP6800 Pro NAS is USB-connected to the UPS and its UPS settings are configured for USB
With this setup, none of the ReadyNAS boxes should power back on after power is restored from an outage. This will prevent the notification chatter I encountered earlier.
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. No experience trying anything like this, and don't want to use a Raspberry Pi just for this.
