I think the old version had UPS support. I have a UPS plugged into the beta system's USB port but was wondering if it is even a feature on this one? I suppose I could go unplug to find out. In any case, it would be nice to see a module in the webadmin UI to configure when to do a safe shutdown.
ASG V7 will have UPS support too (of course). Current BETA does not handle it or show the status, but with the next BETA this will change and you will see a battery icon on your dashboard.
