Chapter 1: Overview
FAN10 and FAN10R Cooling Fans
28
The cooling units for the chassis are the FAN10 and FAN10R fan
modules. Refer to Figure 8.
Figure 8. FAN10 and FAN10R Fan Modules
Here are the fan module guidelines:
The fan modules have different airflow directions. The FAN10
airflow direction is from front to back.
The FAN10R airflow direction is from back to front.
The switch comes with the FAN10 module pre-installed on the rear
panel.
The FAN10R module is sold separately.
Caution
The FAN10R module must be used with the PWR150R power
supply. Using the FAN10R module with any other power supply may
result in inadequate ventilation and cooling inside the switch, which
may cause the device to overheat and fail.
The fan modules contain two fans. If a single fan fails, the switch
may be able to continue operating for up to 24 hours without
overheating, depending on the ambient temperature and
ventilation.
The fan module is field-replaceable and hot-swappable. You do
not have to power off the switch to replace it.
The switch automatically adjusts the fan speeds according to the
ambient temperature.
