vFollow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
vSee the parts listing in the Hardware Maintenance Manual to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU).

CPU | When only the CPU LED is lit, a | 1. | Determine whether the CNFG LED is also lit. If the CNFG |
| microprocessor has failed. | ||
|
| LED is not lit, a microprocessor has failed. | |
|
|
| |
| When the CPU and CNFG LEDs are lit, |
| a. Make sure that the failing microprocessor, which is |
|
| indicated by a lit LED on the system board, is installed | |
| the microprocessor configuration is not |
| |
|
| correctly. See the Hardware Maintenance Manual for | |
| valid. |
| |
|
| information about installing a microprocessor. | |
|
|
| |
|
|
| b. If the failure remains, call service. |
|
| 2. | If the CNFG LED is lit, then an invalid microprocessor |
|
|
| configuration has occurred. |
|
|
| a. Make sure that the microprocessors are compatible with |
|
|
| each other. They must match in speed and cache size. |
|
|
| To compare the microprocessor information, run the |
|
|
| Setup utility and select System Information, then select |
|
|
| System Summary, and then select Processor Details. |
|
|
| b. (Trained service technician only) Replace an |
