Bare metal provisioning is not supported on Intel AMT 6.0 and later systems. These systems will not start sending out hello packets when you first connect them to the power and network. By default, the timer that controls how long the system will send out the hello packets after it is plugged in has been set to 0 so it will timeout as soon as it is plugged in.
To do remote configuration on these systems, use Activator or an ISV client agent (for example on Microsoft System Center Configuration Manager). You can also use the Configurator in Intel SCS 7 to initiate remote configuration on Intel AMT 6 systems. The Intel tools are available on the Tools page in the Intel vPro Expert Center. For information on Microsoft, LANDesk, Symantec, and other ISVs, please check out the home page for the respective software.
