Replacing the Main Chassis Fan
Removing the Fan
1 Switch off the display and PC. Disconnect all power cables and any LAN
or telecommunications cables.
2 Remove the PC’s cover (refer to page 24 for instructions).
3 Disconnect the fan cable from the system board.
4 From the rear of the PC, use a screwdriver to gently push the two
retaining clips inwards, then lift the fan up and out of the chassis.
Replacing the Fan
NOTE Ensure that all cables are clear of the fan and will not easily come into
contact with the fan during normal use or following transportation.
1 The fan unit can only be installed in one way. The distance between the
two retaining clips is shorter at the top than the bottom. Align the fan
clips with their corresponding holes.
2 Gently push the fan downwards until it clicks into place.
3 Connect the fan cable to the main chassis fan connector on the system
board (refer to page 53 for location).
4 Replace the PC’s cover (refer to page 25). Reconnect all the power and
telecommunications cables.
