      Front and rear fan assemblies removal and installation - ThinkStation S20 (type 4105, 4157, 4217)


      Do not open your computer or attempt any repair before reading and understanding the "Important safety information" in the ThinkStation Safety and Warranty Guide that came with your computer.

      This section provides instructions on how to replace the front or rear fan assembly.

      To remove or replace the front or rear fan assembly, do the following:

      1. Remove the computer cover. See "Cover removal".
      2. Locate the fan assembly that you want to replace. Your computer has one front fan assembly and one rear fan assembly. See "Locating major FRUs".
      3. Remove the front bezel if you are replacing the front fan assembly. See "Front bezel removal and installation".
      4. Disconnect the fan assembly cable from the system board. See "Locating parts on the system board".
      5. The fan assembly is attached to the chassis by four rubber mounts. Carefully remove the four rubber mounts by breaking them or cutting them with scissors and then remove the fan assembly out of the chassis.
