Smart UPS Modular Ultra has an IM alarm after toggling the system enable switch

All models, all serial numbers
Resolution:
Perform a full power cycle of the system to clear the IM fault condition and restore normal operation.

Notes
- This behavior can occur with various IM-related faults, not tied to a specific alarm code.
- Symptoms may include:
- IM fault alarms
- IM not operating properly
- Unexpected IM communication or status issues
- If alarms persist after a complete power cycle, please reach out the technical support.
The System Enable (SE) switch should only be used when required for service or troubleshooting activities. Avoid repeatedly toggling the switch and allow the UPS to fully complete its startup and initialization process after re-enabling the system. Improper or repeated use of the SE switch may result in temporary Intelligence Module (IM) initialization alarms during system startup.
