Chapter 5: Chassis Setup and Maintenance
Three 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 SC111 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 SC111 chassis provides two additional open fan housings, where an additional
system fan may be added for optimal cooling.

Remove the dummy fan from the fan tray. 2.

arrows on the top of the fan (indicating air direction) point in the same direc-
tion as the arrows on the other fans.
Connect the fan wires to the fan headers on the serverboard. 4.
Power up the system and check that the fan is working properly before re- 5.
