Erasing lost or forgotten passwords
Notes:
1. To set, change, or delete a password, see Chapter 3, “Using the
Configuration/Setup Utility Program” on page 17.
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 50.
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
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 82 or see the label inside the server.
