To Erase a Password You Do Not Know
You can erase a password by inserting a clear-nonvolatile-RAM
(NVR) jumper. After you insert a clear-NVR jumper, you will
need to reset all environment variables.
To erase a password you do not know,
1.
Turn off the system power.
2.
Install the clear-NVR jumper (part # 12-14314-00). Refer to
the next section for installation directions.
3.
Turn on the system and wait for the console prompt to
appear.
4.
Turn off the system again.
5.
Remove the clear-NVR jumper.
6.
Turn on the system power.
7.
Use the setenv command to reset environment variables to
the values you want.
After you erase the password, the console commands have no
password protection until you set a new password.
Use the setenv command to reset the environment variables.
For an explanation of the setenv command, refer to ‘‘Console
Commands.’’ section in Appendix C.
