To remove and replace a fan
Use this procedure to remove and replace a fan. When necessary, refer to other removal
procedures The graphics in this chapter are representative of the oscilloscope at the time of this
printing. Your unit may look different.
WARNING AVOID INJURY!
The fan blades are exposed both inside and outside the chassis. Disconnect the power cable
before working around the fan. Failure to observe these precautions may result in injury.
Use this procedure to remove and replace the fans. When necessary, refer to other removal
procedures.
1
Disconnect the power cable and remove the top and bottom covers.
2 Disconnect the fan cable from the fan control board. See Figure 6-34.
3 Remove the four Torx T20 fan screws securing the fan to the chassis.

CAUTION AVOID OVERHEATING THE OSCILLOSCOPE!
When replacing the fan, be sure the direction of the fan air flow is coming from the inside to the
outside of the oscilloscope. Check the flow arrows on the fan and check for proper flow once
power is applied to the oscilloscope. Improper air flow can overheat the oscilloscope.
