SC819 Chassis Manual
5-12
Five heavy-duty fans with an optional sixth fan provide cooling for the chassis.
These fans circulate air through the chassis as a means of lowering the chassis
internal temperature.
In models with counter-rotating fans, each fan unit is actually made up of two fans
joined back-to-back, which rotate in opposite directions. This counter-rotating action
generates exceptional airflow and works to dampen vibration levels.
In chassis that provide an additional open fan housing, an additional system fan
may be added for optimal cooling.
Adding a System Fan
1. Power down the system, remove the power cords from the rear of the power
supplies and remove the chassis cover as described in Section 5-3.
2. Remove the dummy fan from the fan tray.
3. Place the new fan into the vacant space in the fan tray while making sure the
arrows on the top of the fan (indicating air direction) point in the same direc-
tion as the arrows on the other fans.
4. Connect the fan wires to the fan headers on the motherboard.
5. Power-up the system and check that the fan is working properly before re-
placing the chassis cover.
