Readynas 314 and Powerware 9130 UPS communication
Hello,
I have a readynas 314 (Firmware 6.8.0) and have established a UPS connection to a Eaton 9130 UPS via internal network/snmp (under Power/UPS).
There are no shutdowm parameters in the configuartion section only basic name/ip etc. I also had to use the "MGE Mib" in that option as none of the 3 powerware selections worked.
I can only assume the UPS sends out a alert at some time prior to turning off when the batteries are gone. There must be some control of the timing here?
Thanks Phil

Hi Marty,
Thanks for that but the original question is not answered. The issue is what settings can the NAS use to shut itself down. I can only assume when a low battery alert is sent from the UPS, the NAS shuts down. There are many alerts sent our on a Eaton UPS.
Thanks Phil
Have you looked at the MIB you selected? I believe it reports
- upsmgBatteryRemainingTime: Remaining battery backup time.
- upsmgBatteryLevel: Battery charge level.
- upsmgBatteryVoltage: Voltage delivered by the battery.
I have no idea which of these signals triggers the NAS shutdown.
But I think the more important question is whether the NAS will actually shut down when the UPS battery drains. Since you aren't sure if the MIB you are using is actually the correct one, I think you need to test it.
I'd connect the NAS directly to the mains power, and put a test load on the UPS (any device you have handy that uses power - incandescent light, space heater, whatever). Then pull the mains plug on the UPS and let it drain. Then keep an eye on when the NAS shuts down.
