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
For additional information about reading your location code, use the following table to link to a specific
topic.
Location code topics that might be of interest
Description
Contains background information on the use of location
codes.
“Physical location codes” on page 150
Provides a definition for physical location code.
“Logical location codes” on page 150
Provides a definition for a logical location code.
“Location code format” on page 150
Provides descriptive information of the Un value in the
location code string. For example U5886.001.
“Location code labels” on page 151
Provides a table that identifies and defines the location
code labels. The location code labels begin with an
alphabetic character and follow the system serial number.
For example, U7879.001.10ABCDE-P3-C31-T2-L23. (The
system serial number is the 10ABCDE in the previous
example.) The P3, C31, T2, and L23 all contain an
alphabetic character that is identified in the Location
code labels table.
“Worldwide unique identifier” on page 152
Provides a definition for the worldwide unique identifier.
This group of digits follows the resource code labels and
always begins with the letter W.
Location code overview
Servers (system unit and expansion units) 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 feature immediately follows the first character
(U5886). Refer to the Unit type and locations table.
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.
