You can identify the enclosure in which a FRU is plugged by its location code. The first character of the location code is always U followed by a four character feature code or enclosure type as shown in the following example: U7879.001.10ABCDE-P3-C31 In this example the enclosure type is 7879.
The next three characters of the location code indicate the model of the enclosure (001 in the example). The next string of characters provides the enclosure serial number (10ABCDE in the example).
Using this information, locate the enclosure with the FRU you want to replace. Find the enclosure type in the following table and go to the Service Guide for that enclosure:
