Usage Information

If you enable the boot access password, the system prompts for a password when you access the GRUB interface.

When you configure the boot access password, ensure that your password meets the following criteria:

  • A minimum of eight characters in length
  • A minimum of one lower case letter (a to z)
  • A minimum of one upper case letter (A to Z)
  • A minimum of one numeric character (0 to 9)
  • A minimum of one special character including a space (" !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~")

If your password does not meet the criteria, the system does not accept your password.

When you upgrade the Dell EMC Networking OS image, ensure that you upgrade the boot loader.

CAUTION After configuring the boot access password, save it to a secure location. If you forget it, you will not be able to access the options in the startup menu. If you forget both the boot access password and the enable password, the system may become inaccessible.
