Fan
A fan mounted inside the ColorPASS chassis draws air into the ColorPASS 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 ColorPASS. If you do not hear the fan, there may be a
faulty power connection (see “To check board and cable connections” on page 4-11).
The following procedures describe how to remove and replace the fan.
TO REMOVE THE FAN
1. Shut down and open the ColorPASS (see page 4-4).
2. Remove the fan cable from motherboard connector FAN3.
3. Release the fan from the fan bracket by bending the hooks on the bracket.

motherboard connector FAN3.
2. Press the fan into bracket until it clicks into place.
Make sure the hooks on the bracket close over the edge of the fan.
3. Connect the fan cable to motherboard connector FAN3.
