1. Check the VRM Error LEDs on the processor board. 2. Turn off the server, reseat the VRM indicated by the lit VRM Error LED, and restart the server. 3. If the problem persists, replace the VRM. 4. Replace microprocessor for that VRM and the companion VRM (see "Processor board component locations" on page 254.) 5. Replace processor board. If the problem persists, go to "General checkout" on page 8. - CPU LED on One of the microprocessors has failed. Actions: 1. Check the Microprocessor Error LEDs on the processor board. Also, if possible, check the System Error Log for additional information. If temperature problems are indicated in the log, check fans. 2. Turn off the server, reseat the microprocessor indicated by the lit Microprocessor Error LED, and restart the server. 3. If the problem persists, replace the microprocessor. 4. Replace both VRMs for that microprocessor. (see "Processor board component locations" on page 254.) 5. Replace processor board. If the problem persists, go to "General checkout" on page 8. - PS1 LED on The primary power supply has failed. Action: Replace the primary power supply. - PS2 LED on The secondary power supply has failed. Action: Replace the secondary power supply. - DASD 1 LED on A hot-swap hard disk drive has failed on SCSI RAID channel 1. Actions: 1. Check the error log for additional information. If the error log indicates a temperature problem and the fans are working correctly, Netfinity 5500 M20 - Type 8662 51
