Error Code Message Information CPU0102 Message CPU temperature is greater than the upper warning threshold. Details System performance may be degraded. Action Check system operating environment, fans, and heat-sinks. CPU0103 Message LCD Message Details Action CPU temperature is greater than the upper critical threshold. CPU temperature is outside of range. Check fans. System performance may be degraded. Check system operating environment, fans, and heat-sinks. CPU0104 Message LCD Message Details Action CPU temperature is outside of range. CPU temperature is outside of range. Check fans. System performance may be degraded. Check system operating environment, fans, and heat-sinks. CPU0200 Message CPU voltage is less than the lower warning threshold. Details Low voltages may be the result of a problem with the voltage regulator or a problem with the processor. The low voltage may cause the processor to fail to operate. Action 1. Turn system off and remove input power for one minute. 2. Reapply input power and turn system on. 3. Ensure the processor is seated correctly. 4. If the issue persists, see Getting Help. CPU0201 Message CPU voltage is less than the lower critical threshold. LCD Message CPU voltage is outside of range. Re-seat CPU. Details Low voltages may be the result of a problem with the voltage regulator or a problem with the processor. When the critical threshold is crossed, the processor will fail to operate. The system may power down. Action 1. Turn system off and remove input power for one minute. 2. Reapply input power and turn system on. 3. Ensure the processor is seated correctly. 4. If the issue persists, see Getting Help. CPU0202 Message CPU voltage is greater than the upper warning threshold. Details High voltages may be the result of problem with the voltage regulator or a problem with the processor. Elevated voltages may result in damage to the processor or other electronic components in side the system. 73
