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.

7043–140 and 7043–150 Fansink Removal and Replacement Procedures
This section contains instructions for removing and replacing defective fansinks on both
the 7043–140 and 7043–150 system boards.
Removing and Replacing the 7043–140 System Board Fansink
Removal
1. Inform the customer that the system must be powered off for approximately one
hour for the fan to be replaced.
2. To power off the system, refer to the ″Removal and Replacement Procedures″
chapter in the RS/6000 7043–43P Series Service Guide . Power off the system as
described in ″Cover Removal″and continue to unlock and remove the cover.
3. Determine the system board assembly part number by noting the white barcode
label attached to the card.
Locate the assembly part number in the leftmost alphanumeric block of characters,
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.
11S 2YL1109140246 FRU 90541L581 41L5912
After you have identified both the system board assembly part number and the FRU
part number, see the table in “Determining the Fansink Assembly Number to be
Replaced” on page 1 to determine the appropriate fan to be replaced.

4. To remove the disk drive bracket, refer to the ″Removing Internal Drive″section of
the
RS/6000 7043–43P Series Service Guide . Carefully place the bracket assembly
on top of the power supply (leave the hard files plugged in).
Note: Disconect temporarily any PCI Adapter Card installed in slot 5 in order to
remove the disk drive bracket.
5. Locate the CPU fansink on the planar under the disk drive and unplug it.
Fansink Location
6. Unclip the heatsink by pushing down and away on the finger tab.
7. Tilt the fansink toward the front of the system and slide the narrow buckle off the
front socket tab.
8. Remove the defective fansink assembly and discard.
Note:
Do not wipe off the remaining thermal grease from the top of the existing
CPU chip on the system board assembly.
Chapter 1. 7043–140 and 7043–150 Fansink Removal and Replacement Procedures 3

Replacement
1. If you are replacing a fansink 09P1125, install the new component by hooking the
side opposite the finger tab and then pushing the finger tab side down until it locks
into position.
OR
If you are replacing a fansink 09P1126, first remove the paper pull tab to expose the
thermal grease underneath. Install the new fansink by hooking the side opposite the
finger tab and then pushing the finger tab side down until it locks into position.
2. Plug the new fansink into the system board connector of the old fansink.
3. Reinstall the disk drive bracket assembly (and any PCI Adapter Cards that were
removed from slot 5).
4. Reinstall the top cover.
5. Power on the system and run diagnostics.

4. To remove the disk drive bracket, refer to the ″Removing Internal Drive″section of
the
RS/6000 7043–43P Series Service Guide .
Note: If a hard file is attached to the disk drive bracket, unplug the hard file before
removing the bracket assembly.
4Supplement to the Service Guide and User’s Guide

5. Locate and unplug the fan and disconnect the fansink assembly power cable from
the CPU fansink connector (J26).
Note: There are two possible fansink connections for this system board: right-angle
finger tabs, and wire springs.
Fansink Location
6. To remove a fansink with right-angle finger tabs, unclip the heatsink by pushing
down and away on the fingertab. Remove the fansink assembly and discard.
Note:
Do not wipe off the remaining thermal grease from the top of the existing
CPU chip on the systemboard.
7. To remove a fansink with wire springs, push down and away on the wire loop to
disengage the fansink assembly. Gently lift the fansink vertically up and off without
rocking the fansink.
Attention: While removing the closed loop fansink, severe damage may occur
which would require replacing the entire system board assembly. To
minimize the risk for system damage, be sure to perform the above
operation
no less than 30 seconds after powering off the system , while
the heatsink is still hot. Warm adhesive between the heatsink and CPU
chip will be less likely to pull the aluminum cap off the chip.
Chapter 1. 7043–140 and 7043–150 Fansink Removal and Replacement Procedures 5

Replacement
1. If you are replacing a fansink 09P1126, first remove the paper pull tab to expose the
thermal grease underneath. Install the new fansink by hooking the side opposite the
finger tab and then pushing the finger tab side down until it locks into position.
OR
If you are replacing a fansink 09P1129, remove the adhesive protective paper on
the bottom of the heatsink and place the fansink assembly into the metal bracket on
the system board assembly. Secure the ends of the wire loop under the edge of the
metal bracket.
2. Plug the new fansink into the system board connector of the old fansink.
3. Reinstall the disk drive bracket assembly.
4. Reinstall the top cover.
5. Power on the system and run diagnostics.
