Clear BIOS Passwords Using Jumper

In general, you should always use the BIOS Setup Utility to clear either the User or Supervisor BIOS password. If necessary, you can also clear the BIOS passwords by connecting a jumper to the server module at boot time. The following procedure provides step-by-step instructions for clearing the BIOS passwords using a jumper.
