Scenario
PoE phones reboot or fail to stay powered after a switch firmware update.
Recommended Resolution Path
- Review PoE budget, LLDP-MED behavior, and any firmware defaults that changed around power class handling.
- Check whether the issue affects one switch model or the whole stack.
- Test with a known-good injector or alternate port to isolate switch versus endpoint.
- If the upgrade introduced the regression, capture the exact version before rollback planning.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
