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
Use this information for the Boot Manager.
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.
Note: Secure Boot, Agentless support for all Intel Xeon™ E5-2600 v3 systems are depended on the
firmware/driver readiness of ServerProven plan options (see http://www.lenovo.com/ serverproven/).
To use the Boot Manager program, complete the following steps:
Step 1. Turn off the server.
Step 2. Restart the server.
Step 3. When the prompt
<F12> Select Boot Device
is displayed, press
F12
.
Step 4. Use the Up arrow and Down arrow keys to select an item from the menu and press Enter.
The next time the server starts, it returns to the startup sequence that is set in the Setup utility.
Starting the backup server firmware
Use this information to start the backup server firmware.
The system board contains a backup copy area for the server firmware. This is a secondary copy of the
server firmware that you update only during the process of updating the server firmware. If the primary copy
of the server firmware becomes damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, change the position of the UEFI
boot backup switch (change switch 1 of the SW4 to the on position) to enable the UEFI recovery mode.
Use the backup copy of the server firmware until the primary copy is restored. After the primary copy is
restored, turn off the server; then, change back the position of the UEFI boot backup switch (change switch
1 of the SW4 to the off position).
