3.Using four screws, attach the fan to the grill plate (Figure 23) so that the fan label faces the plate.

4.Insert the fan/grill plate assembly into the power supply bay so that the cable points downward (Figure 23) from the fan toward the other two power supplies, and so the fan’s label faces out the back of the chassis. This alignment is important to ensure correct airflow direction.

5.Using four screws, attach the fan/grill plate assembly to the chassis (Figure 23).

Removing an Individual System Fan

The subchassis houses up to eight system fans. Not all of these fans are required in standard configurations. If a fan fails, follow this procedure to remove the failed fan.

To Remove an Individual System Fan

1.Observe the safety and ESD precautions in “Static Electricity Precautions” on page 2.

2.Remove the access cover (see “Removing the Access Cover” on page 3).

Note:

Correct airflow direction: The side of each fan is embossed with directional arrows indicating airflow direction. Always note the direction of the arrows on a fan before removing it. You will need this information later when you install a different fan.
