SC119 Chassis Manual
5-16
Five heavy-duty fans provide cooling for the chassis. These fans circulate air through
the chassis as a means of lowering the chassis' internal temperature.
The SC119 chassis contains counter-rotating fans. Each fan unit is actually made up
of two fans joined back-to-back, which rotate in opposite directions. This counter-ro-
tating action generates exceptional airflow and works to dampen vibration levels.
The SC119 chassis provides an additional open space in the fan housing, where
one additional optional system fan may be added for optimal cooling.
Adding a System Fan
1. Power down the system and disconnect the power cords from the rear of the
power supplies. Remove the chassis cover as described in Section 5-2.
2. Remove the dummy fan from the fan tray.
3. Place the new fan into the vacant space in the tray while making sure the ar-
rows on the top of the fan (indicating air direction) point in the same direction
as the arrows on the other fans.
4. Connect the fan wires to the fan headers on the serverboard.
5. Power up the system and check that the fan is working properly before re-
placing the chassis cover.
