This document describes how to change field-replaceable units (FRUs) for switches with either a

A new FRU must have the same part number (P/N) as the FRU being replaced. The
manufacturing P/N is located on the top of the FRU.

You must use a replacement FRU that has the same airflow designator with the part number.
