Installing the operating system without ServerGuide If you have already configured the blade server hardware and you decide not to use the ServerGuide program to install the operating system, you can download the latest operating-system installation instructions from the IBM Support Web page at http://www.ibm.com/pc/support/. Using passwords From the System Security choice, you can set, change, and delete a power-on password. If you set a power-on password, you must type the power-on password to complete the system startup, and to have access to the full Configuration/Setup Utility menu. You can use any combination of up to seven characters (A-Z, a-z, and 0-9) for the password. Keep a record of the password in a secure place. If you forget the power-on password, you can regain access to the blade server through one of the following methods: v Remove the blade server battery and then reinstall it (see "Replacing the battery" on page 50). v Change the position of the power-on password override switch (switch 8 on switch block 2 on the system board) to bypass the power-on password check the next time the blade server is turned on. You can then start the Configuration/Setup Utility program and change the power-on password. You do not need to move the switch back to the previous position after the password is overridden. See Figure 30 on page 61 for the location of switch block 2. Note: Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter unit to access the switches. Starting the PXE boot agent utility program Complete the following steps to start the PXE boot agent utility program: 1. Turn on the server. 2. When the Broadcom NetXtreme Boot Agent vX.X.X prompt appears, press Ctrl+S. Notes: a. If the PXE setup prompt is not displayed, use the Configuration/Setup Utility program to set the enable Ethernet PXE/DHCP option. b. By default, you have 2 seconds after the prompt appears on the screen to press Ctrl+S. 3. Use the arrow keys or press Enter to select a choice from the menu. v Press Esc to return to the previous menu. v Press the F4 key to exit. 4. Follow the instructions on the screen to change the settings of the selected items; then, press Enter. Chapter 3. Configuration 15
