When the system is powered on after a CPU has been replaced or
upgraded, the Global Error indicator will start flashing with the message

is no technical problem.

● Restart your server.
● As soon as the startup screen appears, press the [F2] function key to
enter the BIOS.
● If a password is assigned, enter the password and press [Enter].
● Select the Save & Exit menu.
