This section contains instructions for removing and replacing defective fansinks on both

1. Inform the customer that the system must be powered off for approximately one
hour for the fan to be replaced.

. Power off the system as
described in Cover Removal and continue to unlock and remove the cover.

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.

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
