   If the PAP is used,the HDP is enabled automatically, and no HDP prompt appears.
   The HDP is set the same as the PAP.

•  If the POP is the same as one of the HDPs (HDP-1 or HDP-2), a POP prompt appears. But one of the  HDP prompts does not appear.
•  If the POP is not the same as either of the HDPs (HDP-1 or HDP-2), both prompts appear.
•  If the PAP is used, the HDP-1 or the HDP-2 is automatically enabled, and neither HDP prompt  appears. Both HDP-1 and HDP-2 are set the same as the PAP.

Supervisor and Hard Disk Passwords:

The supervisor password (PAP) and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access.
No overriding capability is provided. If only a hard disk password is set, you must obtain permission from the password owner to unlock the password before running diagnostic tests and performing service.
