To insert the new fan
1 Attach one end of a grounding strap to your wrist and the other end to a grounded metal
surface.
2 Insert the new fan into the fan slot in the bottom of the BCM50 case.
Ensure the fans are oriented such that the airflow is out of the unit.
3 Connect the fan cable to the header.
4 Ensure the fan cable is routed through the cutouts under the hard disk and bracket. Also make
sure that any slack in the fan cable is secured in the clips on the hard disk bracket (see
Figure 77).
Caution: Ensure that you follow the same routing for the cables as before the
component was removed.
Note: Ensure the label of the new fan faces the back of the BCM50 unit. Airflow
is out of the chassis as indicated by the arrows imprinted on the fan.
