15. Reinstall the side cover; then, reconnect all external cables and power cords and turn on the peripheral devices. 16. Turn on the server to restart the operating system. Erasing a lost or forgotten password (clearing CMOS) This section applies to lost or forgotten passwords. For more information about lost or forgotten passwords, see "Passwords" on page 10 Complete the following steps to set the CMOS recovery jumper and erase a forgotten password: 1. Review the safety information beginning on page 129 2. Turn off the server and all attached devices. 3. Unplug the power cord, and disconnect all external cables. 4. Remove the side cover and support bracket. (See "Removing the side cover" on page 36 and "Removing and installing the support bracket" on page 38.) 5. Locate the CMOS recovery jumper (JBAT1) on the system board, removing any adapters that impede access to the jumper. The following illustration shows the location of the jumper on the system board. (J12) Normal Configure 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 Keep data Clear data Recovery (no jumper) Boot block CMOS recovery jumper (JBAT1) recovery jumper (J12) 6. Move the CMOS recovery jumper from pins 1 and 2 to pins 2 and 3. 7. Wait 60 seconds; then, return the CMOS recovery jumper to pins 1 and 2. 8. Replace any adapters that were removed; then, replace the frame-support bracket and replace the side cover. (See "Removing and installing the support bracket" on page 38 and "Replacing the side cover" on page 67) You can now start the server one time without having to use the power-on password and start the Configuration/Setup Utility program. At this time, you can either delete the old password or set a new power-on password. If you do not change or delete the password, the next time you start the server the original power-on password will be reinstated. 28 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide
