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:
Ÿ
Date and time
Ÿ
Security features
Ÿ
Power-management devices
Ÿ
Storage devices
Ÿ
Keyboard and mouse
Ÿ
ISA legacy configuration information
Ÿ
Plug and Play configuration information
Ÿ
Port assignments
Ÿ
I/O addresses and interrupts
Ÿ
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.
