To remove and replace the fans

WARNING AVOID INJURY!

The fan blades are exposed both inside and outside the chassis. Disconnect the power cable

before working around the fan. Use extreme caution in working with the oscilloscope. 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. The graphics in this chapter are representative of the oscilloscope at the time of

this printing. Your unit may look different.

Disconnect the power cable and remove the cover and top plate.

Disconnect the fan harness cables.

Clip off the end of each of the locking buttons (see Figure 5-53) and take the fan out.

Repeat for each fan that needs to be replaced.

Figure 5-53

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.

To install the fan, reverse this procedure.
