administrator password, you do not have to type a password to complete the system startup, but you must type the administrator password to access the Configuration/Setup Utility menu. If you set a power-on password for a user and an administrator password for a system administrator, you can type either password to complete the system startup. A system administrator who types the administrator password has access to the full Configuration/Setup Utility menu; the system administrator can give the user authority to set, change, and delete the power-on password. A user who types the power-on password has access to only the limited Configuration/Setup Utility menu; the user can set, change, and delete the power-on password, if the system administrator has given the user that authority. Power-on password If a power-on password is set, when you turn on the server, you must type the power-on password to complete the system startup. You can use any combination of up to seven characters (A-Z, a-z, and 0-9) for the password. If a power-on password is set, you can enable the Unattended Start mode, in which the keyboard and mouse remain locked but the operating system can start. You can unlock the keyboard and mouse by typing the power-on password. If you forget the power-on password, you can regain access to the server in any of the following ways: v If an administrator password is set, type the administrator password at the password prompt. Start the Configuration/Setup Utility program and reset the power-on password. v Remove the battery from the server and then reinstall it. For instructions for removing the battery, see ″Replacing the battery″ in the Problem Determination and Service Guide. v Change the position of the power-on password jumper (J65 on the I/O board) to bypass the power-on password check. Attention: Before you change any switch settings or move any jumpers, turn off the server; then, disconnect all power cords and external cables. See the safety information that begins on page v. Do not change settings or move jumpers on any switch or jumper blocks that are not shown in this document. The following illustration shows the locations of the power-on password, boot recovery, and Wake on LAN jumpers. 50 IBM System x3755 Type 8877: User's Guide
