System Status LED The system status LED uses colors and blink codes as outlined in the following table. Table 8. System Status LED Color and Blink Codes Color / Blink Pattern Off Green on Green blink Amber blink Amber on Critical Level No issue No issue System degraded Non-critical problem Critical, nonrecoverable problem Description System is not ready System is booted and ready to use The system is not likely to fail soon, but a problem occurred that must be addressed. One of the following problems may have occurred: • More than one DIMM is installed, but system cannot use all of the installed memory. • Correctable memory errors have passed the threshold of 10. Memory sparing is enabled and the system is migrating to a spare DIMM. DIMM redundancy is lost because of this. • The system is in a mirrored configuration and has lost memory redundancy. • A PCI-Express link error has occurred. • A processor has failed or is disabled. • A fan failed. • A temperature or voltage threshold has been crossed. The system is likely to fail. One of the following problems may have occurred • A critical voltage threshold has been crossed. • The minimum number of fans needed to cool the system are not available or not working. • In non-sparing and non-mirroring mode the threshold of ten correctable errors has been crossed within an allotted time window. Fatal alarm - system has failed or shutdown • Only one DIMM is installed and that DIMM has failed, or multiple DIMMs are installed and none is usable. • An uncorrectable rn-time memory uncorrectable error occurred and the system is in a non-redundant mode. • The IERR signal has been asserted. • Processor 1 is missing. • Temperature critical threshold crossed (CPU ThermTrip, memory TempHi) • Power fault • Processor configuration error, such as a processor stepping mismatch) Server System User Guide 115
