System Board LED DIMM 1 Error LED on DIMM 2 Error LED on DIMM 3 Error LED on DIMM 4 Error LED on FAN 1 LED on FAN 2 LED on TEMP LED on Integrated Voltage Regulator Error LED on Secondary Processor VRM Error LED on Primary Microprocessor Error LED on Secondary Microprocessor Error LED on Power Supply 1 LED on Power Supply 2 LED on Description The DIMM in DIMM slot 1 has failed. Action: Replace the DIMM in DIMM slot 1. The DIMM in DIMM slot 2 has failed. Action: Replace the DIMM in DIMM slot 2. The DIMM in DIMM slot 3 has failed. Action: Replace the DIMM in DIMM slot 3. The DIMM in DIMM slot 4 has failed. Action: Replace the DIMM in DIMM slot 4. Fan 1 has failed or is operating too slowly. Note: A failing fan can also cause the TEMP and DASD 1 LEDs to be on. Action: Replace fan 1. Fan 2 has failed or is operating too slowly. Note: A failing fan can also cause the TEMP and DASD 1 LEDs to be on. Action: Replace fan 2. The system temperature has exceeded the maximum rating. Actions: 1. Check to see if a fan has failed. If it has, replace the fan. 2. Make sure the room temperature is not too hot. The voltage regulator for the primary microprocessor slot has failed. Actions: Replace the system board. The voltage regulator module (VRM) for the secondary microprocessor slot has failed. Actions: 1. Turn off the server, reseat the VRM, and restart the server. 2. If the problem persists, replace the VRM. The microprocessor in the primary microprocessor slot has failed. Actions: 1. Turn off the server, reseat the microprocessor, and restart the server. 2. If the problem persists, replace the microprocessor. The microprocessor in the secondary microprocessor slot has failed. Actions: 1. Turn off the server, reseat the microprocessor and VRM; then restart the server. 2. If the problem persists, replace the microprocessor. The primary power supply has failed. Action: Replace the primary power supply. The secondary power supply has failed. Action: Replace the secondary power supply. 46 Netfinity Server HMM
