Shutdown rules on ReadyNas Duo V2 (arm) with connected APC SmartUPS in power breakdown situation
Hello!
I have a ReadyNAS Duo V2 (arm) with firmware 5.3.13. The NAS is connected via a AP9630 network management card 2 to a APC SmartUPS. In the AP9630 the ReadyNAS Duo V2 is configured as snmp tr...
The NAS doesn't need long to shutdown (less than a minute).
You can easily do a test to verify things are working properly. Plug power of the NAS directly into the wall outlet, but connect the SNMP to the UPS. Unplug the power from the UPS and monitor to see when the NAS is shutdown.
Then reconnect the UPS to power and plug the power cable from the NAS into the UPS again.
Hi!
I did the test before und now again with pictures
As you can see the UPS and the NAS are running for 30 minutes without any reaction in a power breakdown situation because the batteries of the UPS are nearly full. For the note I sent alert messages 17.55 and 18.25 which can be seen on the pictures. Then I interrupted the test because I do not want to empty my UPS.
Because of no load at the UPS this test can take a long time until the remaining runtime is low enough or the battery capacity falls under a certain treshold or ... so that the NAS get a signal from the AP9630 in the UPS to shut down.
That is why I ask the above questions: on what information or signal and when will the NAS shutdown?
Well, the information is clearly coming through the SNMP MiB defined by APC. You'd have to look at that to see what is sent.
You could also perform your test safely by
- connecting the NAS to the main power (instead of the APC)
- Put a load on the APC
- Disconnect the APC from main power.
Yes of course , I can do more tests!
But my questions was if anyone knows???
To test it out by myself than I do not have to ask!
Then I would do it on my own and would report it here!
I ask for support not for more testing procedures. This I can build for my own!
