Note: The server does not contain a light path diagnostics panel. System fan 3 error (LED2) System fan 1 error (LED3) Standby power good (LED1) Mini-BMC heartbeat error (LED10) VRD good (LED11) System fan 2 error (LED13) DIMM 4 error (LED14) DIMM 3 error (LED15) DIMM 2 error (LED16) DIMM 1 error (LED17) Use the system-board LEDs to diagnose system errors. Each error LED is lit to indicate a problem with a specific component. After a problem is corrected, its LED will not be lit the next time that the server is restarted; if the problem remains, the LED will be lit again.
