How to recover lost Serial Number and Product ID
If the server loses Serial Number and Product ID, recover them as follows:
(1) Power off the server. Then disconnect the plug from the outlet.
(2) Wait 30 seconds. Then plug the server into the outlet again.
(3) Turn on the server with the POWER button.
(4) The server starts up and the POST screen appears.

If this fails, initialize the RBSU settings with the system maintenance switch (refer to “Chapter 1 7.3.3 Restore the
Default Settings of System Configuration” of the maintenance guide).
(6) Check the values of Serial Number and Product ID by selecting the menu of the System Utilities: System
Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Advanced Service Options.
(7) If the values of Serial Number and Product ID are satisfactory, go to step 14.
(8) If the values are unexpected or lost, select the menu of the System Utilities: System Configuration > BIOS/Platform
Configuration (RBSU) > System Default Options.
(9) Select the Restore Default Manufacturing Settings option.
(10) Select this option: Yes, restore the default settings.
(11) The server restarts automatically and the POST screen appears.
(12) Press the F9 key to enter the System Utilities.
(13) Set the proper Serial Number and Product ID (indicated on the pull-out tab of the server) via the menu of the System
Utilities: System Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Advanced Service
Options.

Product ID is the model number like "N8100-2640F". Product ID is not PID.
