Changing or Clearing the Supervisor Password
Using the System Setup utility, you can change or clear a supervisor password for the BIOS Setup utility. The password is required when the system is booted,
or when the user enters the BIOS Setup utility. A supervisor has access to all features in the BIOS Setup utility.
To change a supervisor password, perform the following steps:
1. Connect a keyboard, monitor, and mouse to the system.
2. Turn on or restart your NAS system.
Press <F2> immediately after you see the following message:
Press <F2> to enter the Function Select menu.
If you wait too long and your operating system begins to load into memory, allow the system to complete the load operation, and then shut down the
NAS system and try again.
3. When the Function Select menu appears, press <1> to run the System Setup utility.
4. From the main menu, select Security.
5. Select Change System Password and press <Enter>.
6. Enter the old password in the dialog box that appears.
7. When prompted, enter the new password (no more than six letters or numbers); or, to clear a password, leave this field blank.
8. Press <Enter>.
9. When prompted, select either Setup or Always. If you select Setup, the password will only be requested when entering the System Setup utility. If you
select Always, the password will be requested anytime the system is rebooted.
10. To confirm the new password, enter the password again in the dialog box that appears.
11. Press <Enter>.
