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 specic information regarding the fault, and follow any Recommended Actions.
• If installing an IOM CRU:
– Remove and reinstall the IOM per the instructions in Removing an 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 ME Storage Manager or CLI.
– If the restart does not resolve the fault, remove the IOM and reinsert it.
