Erasing lost or forgotten passwords Erasing lost or forgotten passwords Note: To set, change, or delete a password, see "System 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 administrator password, you must erase all configuration and setup information by moving the jumper designated for CMOS memory. This jumper is known as the Clear CMOS Request jumper. Attention administrator password users: 1. If enhanced security is enabled, and you forget or lose the administrator password, you must replace the system board in your server to regain access to the Configuration/Setup Utility program. For more information, see "Using the Enhanced Security features" on page 50. 2. Clearing CMOS memory erases the configuration of your server. Therefore, you must reconfigure the server after clearing CMOS memory. If possible, record your server configuration information before moving the Clear CMOS Request jumper. 254 Netfinity 3000 User's Handbook
