Finding parts, locations, and addresses

Locate physical part locations and identify parts with system diagrams.

You can identify the enclosure in which a field-replaceable unit (FRU) is plugged by its location code. The first character of the location code is always U followed by a 4–character feature code or enclosure type as shown in the following example: U78CB.001.10ABCDE-P3-C31 In this example, the enclosure type is 78CB.

The next 3 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.

Locate the FRU

The string of characters that follow the enclosure serial number identifies the FRU location within the enclosure: U78CB.001.10ABCDE-P3-C31 In this example, P3-C31 is the location of the FRU to be replaced. Use the graphics and tables to locate the FRU and link to its removal and replacement procedure.
