2. Orient the oscilloscope: Set the oscilloscope so the bottom is down on the
work surface and the left side is facing you.
3. Remove the fans: See Figure 6--20,on page 6--39.
a. Remove the four plastic fasteners that secure each of the fans to the
chassis. See Figure 6--20.
NOTE. A wire cutter can help you remove each fastener. First, use the cutter to
pry up and retract the fastener head. Then use it to remove the fastener body.
Be careful to only pry with the wire cutters and NOT to cut!
b. Lift the fan cable up and out from the cable clamp.
NOTE. Needle-nose pliers can serve as an effective tool to remove the cable
clamp if you use it to carefully squeeze the clamp’s top and bottom latches.
c. Disconnect the fan cable from the PC interface board. See Figure 6-- 21
on page 6--40.
d. Lift the fan assembly up and out from the chassis.
4. Reinstallation: Do in reverse steps a through d to reinstall the fan assembly.
CAUTION. Take care when handling the fans; the fan blades are brittle and can be
easily damaged.
