Troubleshooting Your System 137
13 Run the appropriate Embedded System diagnostic test. See "Running the
System Diagnostics" on page 139.
If the test fails, the processor is faulty. See "Getting Help" on page 149.
14 Turn off the system and attached peripherals, and disconnect the
system from the electrical outlet.
15 Open the system. See "Opening the System" on page 60.
16 Replace processor 1 with processor 2. See "Installing a Processor" on
page 99.
17 Repeat step 11 through step 13.
If you have tested both the processors and the problem persists, the system
board is faulty. See "Getting Help" on page 149.
