UPS alerts but graceful shutdown never triggers

Scenario

Power events generate notifications from a UPS, but protected systems do not shut down gracefully.

Verify the management daemon or NUT/appliance software is running and linked to the correct UPS.
Test communication over USB or network from the shutdown agent host.
Review low-battery and shutdown threshold settings for unrealistic values.
Run a controlled test window instead of assuming alerts equal safe shutdown.

Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
