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

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.
