1 Align the cooling fan with the sponge and slide it in the cooling-fan
cage until the cooling fan is firmly seated. See Figure 3-5.
NOTE: The fan blades should face the front panel of the system.
2 Connect the fan cable to the connector on the cooling-fan cage.

place it into the chassis until it’s firmly seated in place. See Figure 3-4.

distribution board 1. See Figure 3-4.
You must route these cables properly through the ties to prevent them
from being pinched or crimped.
