6-3 System Cooling
Six heavy-duty fans provide cooling for the chassis. Four fans are located in the
mid-section of the chassis and two fans are located in the rear. These fans circulate
air through the chassis as a means of lowering the chassis internal temperature.
The fans come pre-installed to the chassis. Each fan is hot-swappable and can be
replaced without removing any connections.
System Fan Failure
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining
fans will ramp up to full speed. Replace any failed fan at your earliest convenience
with the same type and model (the system can continue to run with a failed fan).
Replacing System Fans
The SC747 chassis contains two types of system fans: mid-system fans and rear
system fans.
Replacing Mid-System Fans (FAN-0114L4)
1. Determine which fan has failed. Because the fans are hot-swappable, the
chassis does not need to be powered-down.
2. Press the fan release tab and lift the failed fan from the chassis. Mid fans
must be pulled straight out of the chassis (see Figure 6-3). Part numbers: four
fans are FAN-0114L4.
3. Place the new fan into the vacant space in the housing while making sure
the arrows on the top of the fan (indicating air direction) point in the same
direction as the arrows on the other fans. As soon as the fan is connected, it
will begin working.
Replacing the Rear System Fan (FAN-0082L4)
1. Determine which fan has failed.
2. Press the rear fan release tab (see Figure 6-4).
3. Pull the fan away from the chassis by pulling out the top first.
4. Place the new fan in the chassis, inserting the bottom of the fan first.
5. Push the fan fully into the housing until the fan clicks into place.
