3. (Trained service technician only) Make sure that microprocessor 1 is seated
correctly.
4. Reseat the following components:
a. (Trained service technician only) Microprocessor 1
b. Microprocessor tray
5. (Trained service technician only) If there is no indication of which
microprocessor has failed, isolate the error by testing with one microprocessor
at a time.
6. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. (Trained service technician only) Microprocessor 1
b. (Trained service technician only) Microprocessor tray
7. (Trained service technician only) If multiple error codes or EasyLED LEDs
indicate a microprocessor error, reverse the locations of two microprocessors to
determine whether the error is associated with a microprocessor or with a
