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 (user) password is set, 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 (see "Administrator password" on page 71). 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 the Problem Determination and Service Guide on the IBM Documentation CD. v Change the position of the power-on password override jumper (J37) on the system board to bypass the power-on password check. See "Passwords" on page 69 for additional information. 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 v. Do not change settings or move jumpers on any switch or jumper block that is not shown in this document. The following illustration shows the locations of the power-on password override, boot recovery, and Wake on LAN bypass jumpers. 70 System x3655 Type 7985: User's Guide
