Troubleshooting Abnormal LED States
Troubleshooting Abnormal LED States
Hardware or software faults can prevent the green power-on LED on a CRU from
lighting when power is applied. If the amber service LED for a CRU lights and remains
lit, the CRU cannot be accessed. A fault might have been detected, or the CRU might
not have been successfully initialized and configured for use as a system resource.
Note. For troubleshooting abnormal LED states displayed in IOAM enclosures or FCDMs,
contact your service provider trained by HP.
