■ Chassis fan
One chassis fan is installed in the imagePASS, near the service board. Use the following procedures to remove or replace the
fan.
● To remove the chassis fan
1. Access and open the imagePASS, as described on “Accessing the imagePASS” on page 16 .
2. Disconnect the 4-pin fan cable connector from the motherboard.
3. Remove the four plastic rivets that attach the fan to the chassis, and remove the fan.
To remove a rivet, use a flathead screwdriver to pry loose the rivet head on the outside of the chassis while squeezing and
pushing the locked end of the rivet with your fingers or a pair of pliers. Set the rivets aside so that you can replace them later.
