How to Identify My Intel® Xeon® Processor Markings for Warranty Requests


Last Reviewed: 21-Apr-2017
Article ID: 000005965

The following information helps you identify server processor markings. Processor markings let customer support know if you are eligible for a warranty exchange.

Where do I find the processor markings?
All Intel® Server Processors have markings inscribed on the top of the processor package. The most recent Intel® Server Processor packages and markings are described here.

The serial number is required for warranty processing. The serial number of a processor is typically a combination of the finished process order (FPO) number and the assembly test process order (ATPO) number. If the ATPO Number is not present, provide the FPO number.

If you have the FPO number and ATPO numbers in hand, check your warranty coverage online at the Warranty Center.

If you are not sure about the processor package or socket for your processor, collect the processor markings and Contact Support.
