The information provided in this topic defines specific sections of a location code string. Use this
information to understand the meaning of a location code.
Using location codes
This topic also provides information about how to read and understand the specific sections of a location
code string. A comprehensive list of location codes used by your I/O enclosure is also provided.
Use the following table to link to a specific topic for additional information when reading and
understanding your location code.

Location code overview
Servers (system unit and enclosures) use physical location codes to provide mapping of replaceable units.
Location codes are produced by the server's firmware, which structures them so that they can be used to
identify specific parts in a system. The location code format is the same for all servers.
If you are working with a specific location code, the unit type and model immediately follow the first
character (Utttt.mmm). Match the unit type and model to a link, as shown in the Unit type and locations
table.
v If the location code ends with -Txx-Lxx, the server's firmware could not identify the physical location.
When a physical location cannot be identified, a logical location code is provided. Where logical
location codes occur in enclosures, the locations topic for the enclosure has the known conversions
listed. For logical location codes with no conversion, contact your next level of support.

Finding parts, locations, and addresses
Description
Contains background information about using location
codes.
Provides definitions for physical location codes.
Provides definitions for logical location codes.
Provides format information of the Un value in the
location code string. For example U7031.001.
Provides definitions for location code labels. The location
code labels begin with an alphabetic character and follow
the system serial number. For example,
U7031.001.10ABCDE-P3-C31-T2-L23. (The system serial
number is the 10ABCDE.) The P3, C31, T2, and L23 all
contain an alphabetic character that is identified in the
Location code labels table.
Provides definitions for the worldwide unique
identifiers. This group of digits follows the resource code
labels and always begins with the letter W.
