Chapter 1. 7043–140 and 7043–150 Fansink Removal and

Replacement Procedures

This chapter provides information on replacing defective 7043–140 and 7043–150

fansinks without having to replace the entire system board.

Identifying the Fansink Number

The following table contains information to help you determine the correct fansink to be

replaced on both the 7043–140 and 7043–150 system boards. Obtain the correct fan(s)

before going on-site to replace the fansink assembly. The fan that is not used should be

returned to the parts depot. The defective fan should be disposed of locally.

following the first three characters, which are always 11S. In the following example,

the assembly part number is 41L5812.

The FRU part number is in the center alphanumeric block of characters, following

the first three characters which are always FRU. In the following example, the FRU

part number is 41L5912.
