Step 1542-3
The system is unable to boot standalone diagnostics.
Check the service processor error log and the media subsystem operator panel for additional error codes
resulting from the slow boot in "Step 1542-1". Did the slow boot generate a different error code from the
one that originally sent you to MAP 1542?
NO It appears you have a processor subsystem problem. Call for support. This ends the procedure.
YES Restore fast-boot mode (select Enable Fast Boot) on the System Power Control menu from the
service processor main menu. Go to "Checkpoints and Error Codes Index" on page 394, and
