3).
4. Wait five seconds.
5. Move the jumper back to the default position (covering pins 1 and 2).

The system will automatically power on after AC is applied.
7.3.2

Clearing the Password

This jumper causes both the User password and the Administrator password to be cleared if they were set. The operator should be
aware that this creates a security gap until passwords have been installed again through the <F2> BIOS Setup utility. This is the
only method by which the Administrator and User passwords can be cleared unconditionally. Other than this jumper, passwords
can only be set or cleared by changing them explicitly in BIOS Setup or by similar means. No method of resetting BIOS
configuration settings to default values will affect either the Administrator or User passwords.
To clear the password, perform the following steps:
1. Power down the server. For safety, unplug the power cord(s).
2. Remove the system top cover.
