IBM 2274 manual Power-On Password

Power-On Password

A power-on password denies access to the system by an unauthorized user when the system is powered on. When a power-on password is active, the password prompt appears on the screen each time the system is powered on. The system starts after the proper password is entered. See “Power-On password” on page 21 for more information about how to change, remove and set password in Configuration/Setup Utility.

In some cases, you might be required to service a system with an active and unknown power-on password.To clear a password from the system, follow these steps.

1.Turn off system unit.

2.Unplug power cable from the electrical outlet.

IMPORTANT: Do not attempt these steps with the power cord plugged into the electrical outlet. The power supply maintains +5 Vdc of standby power when the power cord is plugged. System damage might result if the power cord is not unplugged during jumper setting.

3.Set JP14 to 2-3 position to clear BIOS setting as original manufacture setting. See “System Board Jumpers and Connectors” on page 109.

4.Set JP7 back to the 1-2 position to enable password check process. See “System Board Jumpers and Connectors” on page 109.

IMPORTANT: To reinstall the password, the user must enter a password in the Configuration/Setup Utility. If Enhanced Security is enabled and the password is forgotten, the system board must be replaced.
