REPLACING PARTS 72
Fan
A fan mounted inside the E-43A chassis draws air into the E-43A to cool components. The
fan runs continuously when the system is on. You should hear the fan start as soon as you
power on the E-43A. If you do not hear the fan, there may be a faulty power connection.
The following procedures describe how to remove and replace the fan.
TO REMOVE THE FAN
1 Shut down, and then open the E-43A (see pages 43 and 44).
To access the fan, you must remove the left panel.
2 Remove the fan cable from motherboard connector J20.
3 Release the fan from the fan bracket by bending the hooks on the bracket.

4 Remove the fan from the chassis.
TO REPLACE THE FAN
1 Align the fan.
An arrow on the side of the fan indicates the airflow direction. Make sure that the fan is
positioned so that the arrow points inside the E-43A and the fan cable extends downward
toward the motherboard (see Figure 27).
2 Press the fan into the bracket until it clicks into place.
Make sure that the hooks on the bracket close over the edge of the fan.
3 Connect the fan cable to motherboard connector J20.
4 Reassemble the E-43A and verify its functionality (see page 86).
