Troubleshooting a Microprocessor 
Problem 
l Error message indicating a microprocessor problem 
 
l Front-panel status LCD indicating a problem with microprocessors, VRMs, or the system board 
 
l A heat sink is not installed for each microprocessor 
 
Action 
1. Observe the precautions in "Safety First—For You and Your System."  
 
2. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.  
 
3. Remove the cover (see "Removing the Cover").  
 
4. Ensure that VRMs are properly installed for each microprocessor (see Figure6-9).  
 
5. Replace the cover (see "Replacing the Cover").  
 
6. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.  
 
7. Run Quick Tests in the system diagnostics.  
 
If the problem persists, continue to step 8. 
8. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.  
 
9. Remove the cover (see "Removing the Cover").  
 
10. Remove microprocessor 2 and VRM 2, leaving microprocessor 1 and VRM 1 installed (see "Adding or Replacing a Microprocessor" in "Installing System 
Options"). To locate microprocessor 1 and VRM 1, see FigureA-3.  
 
If there is only one microprocessor installed, see "Getting Help." 
11. Replace the cover (see "Replacing the Cover").  
 
12. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.  
 
13. Run Quick Tests in the system diagnostics.  
 
If the tests complete successfully, continue to step 14. 
14. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.  
 
15. Remove the cover (see "Removing the Cover").  
 
16. Reinstall microprocessor 2 and VRM 2 you removed in step 10 (see "Adding or Replacing a Microprocessor" in "Installing System Options").  
 
17. Run Quick Tests in the system diagnostics.  
 
If the problem persists, see "Getting Help." 
Troubleshooting Expansion Cards 
Problem 
NOTICE: The cooling fans are hot-pluggable. To maintain proper cooling while the system is on, replace only one fan at a time. 
NOTE: After installing a new fan, allow up to 30 seconds for the system to recognize the fan and determine whether it is working properly. The fan 
status indicator on the system board will turn green to signify that the fan is functioning properly (see Figure2-7). 
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
