## Verify Processor Module Functionality

1. If you replaced a faulty processor module, use the `show faulty` command to determine if the replaced processor module is shown as enabled or disabled:

       -> show faulty

   1. If the output from the show faulty command shows the replacement processor module as enabled, go to Step 2.
   2. If the output from the show faulty command shows the replacement processor module as disabled, go to Detecting and Managing Faults to clear the PSH-detected fault from the server.
2. Power on the server.

   See Returning the Server to Operation.

3. Verify that the OK LED is lit on the processor module and that the Fault LED is not lit.

   See Processor Module LEDs.

4. Verify that the front and rear Service Required LEDs are not lit.

   See Front Panel System Controls and LEDs and Rear I/O Module LEDs.

5. Perform one of the following tasks based on your verification results:
   - If the previous steps did not clear the fault, see Diagnostics Process.
   - If Step 3 and Step 4 indicate that no faults have been detected, then the processor module has been replaced successfully. No further action is required.
