Chassis Fan Replacement Guide
5.
Connect the new fan to the inline connector. Place the fan inside the fan
bracket with the square slot oriented as shown in Figure 3. The air flow
direction is into the chassis, so the plastic grill and label on the fan
should face toward the PXI card cage.
Place the screen below the fan (see Figure 1 for screen location).
Ensure that the loose screen doesn’t fall out. If the screen does fall out,
return it to its position under the fan.
