Fan module installation
The fan modules in the S4100–ON Series switch are field replaceable.
When looking at your switch, Slot 1 is on the left side of the switch and Slot 4 is on the right side of the switch.
CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction—reverse or normal. If
you mix the airflow direction, to avoid overheating the switch, correct the mixed airflow.
1. Take the fan module out of the shipping box.
2. Slide the module into the bay.
