System Fans

Figure 5-13. System Fans in the Fan Tray with Optional Fifth and Sixth Fans
Four 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 SC116 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 SC116 chassis provides two additional open fan housings, where additional
system fans may be added for optimal cooling.
Adding a System Fan
1. Power down the system and remove the power cords from the rear of the
power supplies. 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 housing 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 serverboard.
5. Plug the power cords into the rear of the power supplies, power up the sys-
tem and check that the fan is working properly before replacing the chassis
cover.
