AMT System Phases
An AMT system can be in one of three phases in regards to its current stage of
AMT Setup and Configuration.
Three Phases of AMT Setup and Configuration:
• Factory
• In-Setup
• Operational
The Factory phase is the initial stage. The system had been built from the factory.
No AMT Setup and Configuration has been done. The only way to access AMT in
Factory phase is through the MEBx. This phase will end for Manual mode systems
once the default password has been changed. Enterprise mode systems also
require the Provisioning ID (PID) and Provisioning Passphrase (PPS) to be set. More
details on passwords, PIDs, and PPS in later sections.
The In-Setup phase is the next stage where most AMT options are set. This can be
a manual procedure or an automated one with a Setup and Configuration Server.
The Operational phase is the final stage. AMT is fully Setup and Configured in the
system and ready for normal use.
Manual Mode – AMT Setup and Configuration with MEBx
Manual mode is for customers who do not have Independent Software Vendors
(ISV) management consoles, or the necessary network and security infrastructures to
use encrypted Transport Layer Security (TLS). Manual mode AMT Setup and
Configuration is a manual process done through the Intel ME BIOS Extension
(MEBx).
Manual mode is the easiest to implement since it does not require much
infrastructure, but it is the least secure since all network traffic is not encrypted. HP
recommends that this be done in a closed network.
Important Note:
The MEBx is an option ROM module that is provided to
HP by Intel to be included in the HP system BIOS. The
MEBx is not HP-specific and contains options that are not
used by HP. If an option is not used by HP, ignore it and
do not modify from its default state.
MEBx passwords must meet the minimum criteria to be accepted. These restrictions
are enforced by the MEBx to reduce vulnerability of passwords to a dictionary
attack.
