Reboot without upgrade

I had a similar situation - it stopped responding to commands to set the backup reserve percentage - but the web UI was still working. I logged in via the web UI, and there was an upgrade staged, ready for upgrade. My guess is that when it downloads an upgrade, but is in use, it stops responding to reserve setting commands until the upgrade is complete. I will confirm shortly when the software should attempt to set the reserve to 100% once it reaches 100% SOC.
