Lenovo 3797 manual Using the Boot Manager program, Administrator password

Attention: Before changing any switch settings or moving any jumpers, turn off the server; then, disconnect all power cords and external cables. See the safety information that begins on page vii. Do not change settings or move jumpers on any system-board switch or jumper blocks that are not shown in this document.

While the server is turned off, move switch 5 of the switch block (SW3)
4 to the On position to enable the power-on password override. You can then start the UEFI Setup Utility program and reset the power-on password. You do not have to return the switch to the previous position.

The power-on password override jumper does not affect the administrator password.

Administrator password

If an administrator password is set, you must type the administrator password for access to the full UEFI Setup Utility menu. You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for the password.

Attention: If you set an administrator password and then forget it, there is no way to change, override, or remove it. You must replace the system board.

Using the Boot Manager program

The Boot Manager program is a built-in, menu-driven configuration utility program that you can use to temporarily redefine the first startup device without changing settings in the Setup utility.

To use the Boot Manager program, complete the following steps:

1.Turn off the server.

2.Restart the server.

3.When the prompt <F12> Select Boot Device is displayed, press F12. If a bootable USB mass storage device is installed, a submenu item (USB Key/Disk) is displayed.

4.Use the Up arrow and Down arrow keys to select an item from the Boot Selection Menu and press Enter.

The next time the server starts, it returns to the startup sequence that is set in the Setup utility.
