Actions:

If the Ops panel Module Fault LED is on, check the module LEDs on the enclosure rear panel to narrow the fault to a CRU, a connection, or both.
Check the event log for specific information regarding the fault, and follow any Recommended Actions.
If installing an IOM CRU:
- Remove and reinstall the IOM.
- Check the event log for errors.
If the CRU Fault LED is on, a fault condition is detected.
- Restart this controller from the partner controller using the PowerVault Manager or CLI.
- If the restart does not resolve the fault, remove the IOM and reinsert it.
