CPU LED lights up

When only the CPU LED lights up, a microprocessor has failed.
When the CPU and CNFG LEDs light up, an invalid microprocessor configuration has occurred.
Troubleshooting steps
Procedure
1. Determine whether the CNFG LED also lights up.
• If the CNFG LED does not light up, a microprocessor has failed.
• If the CNFG LED lights up, then an invalid microprocessor configuration has occurred.
2. Replace the server if the microprocessor has failed.
3. Make sure that the microprocessors are compatible with each other if the microprocessor
configuration is invalid.
