capabilities of the server.
Wrong characters appear on the
screen.
1. Verify that the language and locality settings are correct for the keyboard and
operating system.
2. If the wrong language is displayed, update the server firmware to the latest
level (see “Updating the firmware” on page 121) with the correct language.
