8For systems with multiple processors, turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
9Open the system. See "Opening the System" on page 82.
10Remove all processors except for processor 1. See "Removing a Processor" on page 126.
11Close the system. See "Closing the System" on page 83.
12Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.
13Run the appropriate online diagnostic test. See "Running the System Diagnostics" on page 163.
If the test fails, the processor is faulty. See "Getting Help" on page 167.
14Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
15Open the system. See "Opening the System" on page 82.
16Replace processor 1 with processor 2. See "Installing a Processor" on page 129.
17Repeat step 11 through step 13.
If your system has more than two processors, continue installing and testing each processor in the processor 1 slot until you determine the faulty processor, and then replace the faulty processor. See "Getting Help" on page 167.
If you have tested all the processors and the problem persists, the system board is faulty. See "Getting Help" on page 167.
