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).
Notes:
- On a single-node system, the characters of the location code that indicate the model might be replaced with ND1.
- On a 9080-M9S system, the model number might be replaced by a more specific enclosure indicator. SC1 indicates the system control unit, and ND1 through ND4 indicate system node 1 through system node 4.
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.
| Enclosure number | System |
|---|---|
| U78D3.mmm, where mmm is 001 or ND1 | 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S |
| U78D2.mmm, where mmm is 001 or ND1 | 9009-41A, 9009-41G, 9009-42A, 9009-42G, 9223-42H, or 9223-42S |
| U78D4.mmm, where mmm is 001 or ND1 | 9040-MR9 |
| U78D6.SC1 | 9080-M9S system control unit |
| U78D5.mmm, where mmm is ND1, ND2, ND3, or ND4 | 9080-M9S system node |
| U5887.001 | 5887 disk drive enclosure |
| U78CD.001 | EMX0 PCIe Gen3 I/O expansion drawer |
| UESLL.001 | ESLL disk drive enclosure |
| UESLS.001 | ESLS disk drive 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.
