SC113M Chassis Manual
4-14
The SC113M chassis includes four heavy-duty fans, with open slots for two addi-
tional fans, to provide cooling for the chassis. These fans circulate air through the
chassis and lower the internal temperature within the chassis.

Figure 4-12. System Fan
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 SC113M 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-
rotating action generates exceptional airflow and works to dampen vibration levels.
The SC113M 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 cord from the rear of the
power supply. Open the chassis cover as described in Section 4-3.
2. Remove the screws securing the fan tray to the chassis.
3. Remove the dummy fan from the fan tray by pushing it up from the bottom.
4. 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.
5. Secure the fan tray to the chassis using the screws removed previously.
6. Connect the fan wires to the fan headers on the serverboard.
7. Power-up the system and check that the fan is working properly before re-
placing the chassis cover.
