Erasing lost or forgotten passwords Notes 1. To set, change, or delete a password, see "Using the Configuration/Setup Utility Program" on page 19. 2. When enhanced security is enabled, you cannot erase the administrator password. If you forget or lose the administrator password, the system board in your server must be replaced in order to regain access to the Configuration/Setup Utility program. For more information on enhanced security, see "Enhanced security" on page 43. Your server uses complementary metal-oxide semiconductor (CMOS) memory on the system board for storing configuration and setup information. CMOS memory maintains information about: Date and time Security features Power-management devices Storage devices Keyboard and mouse ISA legacy configuration information Plug and Play configuration information Port assignments I/O addresses and interrupts Other selectable features Within the security features are the settings for the power-on and administrator passwords. If you need to erase a lost or forgotten password, you must erase all CMOS configuration and setup information by moving the jumper designated as Clear CMOS Request. To locate this jumper, see "Identifying parts on the system board" on page 80 or see the label inside the server. Important Clearing CMOS memory erases the configuration of your server. Therefore, you must reconfigure the server after clearing CMOS memory. If possible, record the configuration information of your server before moving the CMOS jumper. 122 Netfinity Server HMM
