Erasing Lost or Forgotten Passwords
Erasing Lost or Forgotten Passwords
Note: To set, change, or delete a password, see System Security.
The 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:
- If enhanced security is enabled, and you forgot 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'.
- Clearing CMOS memory erases the configuration of your server. Therefore, you must reconfigure the server after clearing CMOS memory.
If possible, record the server configuration information before removing the Clear CMOS Request jumper.
The JUMPER is located on the system board with the label Clear CMOS Request.
To locate this jumper, see
Note:
- Using the Configuration/Setup Utility program, record all configuration information.
- Read
Safety Information.
- Power-off the server, but do not disconnect the cables.
- Remove the server cover
- Place the server on its side
- Locate the Clear CMOS Request jumper (J9) on the system board
You might have to remove adapters to gain access to the jumper.
- Move the jumper from its normal position (pins 1 and 2) to pins 2 and 3. It might be helpful to use needlenose pliers to move
the jumper, but be careful not to scrape any system board components or to crush the jumper.
- Power-on the server back on for approximately 10 seconds
- Power-off the server
- Power-on the server back on
- CMOS memory is now cleared and the passwords have been erased. After the POST completes, configuration error messages are displayed.
Note: You might not be able to power-off the power using the power switch until POST is nearly complete.
Unplug the power cord to power-off the server.
- Follow the instructions on the screen to continue.
- When the Configuration/Setup Utility program starts, make the necessary changes, save the settings, and exit setup.
You must update the server configuration. When you see a message that instructs you to move the jumper to the normal position, Power-off the
server.
- Disconnect the power cord from the rear of the chassis.
- Remove the server cover, and move the jumper back to its normal position (pins 1 and 2).
- After clearing CMOS memory, you must reconfigure the server. After reassembling the server (see
Completing the Installation),
use the Configuration/Setup Utility program to reset the date and time, reset any passwords, and reconfigure the server.
For more information, see Configuration/Setup Utility Program Menus.
