Dell Precision M4500 Administrator's Manual page 39

Setting the PID/PPS will cause a partial unprovision if the setup and configuration is "In-process". The PID and PPS should be
entered in the dash format. (Ex. PID: 1234-ABCD ; PPS: 1234-ABCD-1234-ABCD-1234-ABCD-1234-ABCD).
NOTE:
A PPS value of '0000-0000-0000-0000-0000-0000-0000-0000' will not change the setup configuration state. If
this value is used, the setup and configuration state will remain 'Not-started'.
Deleting PID and PPS
Under the Intel TLS PSK Configuration menu, select Delete PID and PPS and press Enter.
This option deletes the current PID and PPS stored in Intel ME. If the PID and PPS were not entered previously, the Intel
MEBx will return an error message.
To delete the PID and PPS entries, select Y, else N.
