   1. Lift the failed fan out the SSA.
      See Disconnecting an F11-F13 Fan (Fan F11 Example).

      

      Disconnecting an F11-F13 Fan (Fan F11 Example)

      

      1 = Fan F11 connector	3 = Rubber grommet
      2 = Fan F11

   2. Remove the failed fan‘s cables from the rubber grommet.
      You might have to lift the rubber grommet out of the chassis to remove the failed fan‘s cables from the grommet. The grommet is slit.
   3. Disconnect the fan from the appropriate connector.
      The bank of F11-F13 connectors is located next to fan F11, on the other side of the sheet metal wall that separates the power supply bays from the rest of the SSA. If you are facing toward the back of the SSA, the F11-F13 connectors are arranged as follows:

      • F11 connector: left connector
      • F12 connector: middle connector
      • F13 connector: right connector
5. Unwind the replacement fan‘s cables.
6. Remove the cable clip from the replacement fan.
   See Removing a Fan‘s Cable Clip.

   You may discard the cable clip.

7. With the label side of the replacement fan facing into the second power supply bay (labeled PS2) and the cable on the left, slip the fan cable into the rubber grommet and connect the cable to the chassis connector.
   See Connecting an F11-F13 Fan (Fan F11 Example).

   2 = Fan F11

8. Position the fan in the SSA.
9. Position the cables of the F11-F13 fans on top of the fans, ensuring that the cables are not in a position that would cause the cables to be pinched by the rear panel.
10. Reinstall the rear panel of the SSA.
