Troubleshoot/Problem Solving 119
The Ops panel LEDs are defined in Tabl e 13 .
Actions:
• If the Ops panel Module Fault LED is on, check the module LEDs on the chassis 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 a RAID controller or expansion IOM CRU:
• Remove and reinstall the CRU per Replacing a 2U RAID Controller or an Expansion IOM on
page 179.
• 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 disk management utility or CLI.
• If the restart does not resolve the fault, remove the RAID controller or expansion IOM and
reinsert it.
• If the above actions do not resolve the fault, contact Quantum for assistance.
