Fans
The Z9432F-ON switch comes from the factory with seven fan modules that are installed in the switch. The fan modules, which
have integrated fans, are hot-swappable.
Besides the power supply modules, you can order and install fan modules separately.
The Z9432F-ON switch supports two airflow direction options. To avoid damage to the switch, do not mix airflow types in a
switch; you can use only a single airflow direction in a switch. If the airflow directions are mismatched,
you must correct the
mismatched airflow direction
.
CAUTION:
Switches with fan airflow from the PSU to the I/O—reverse airflow—are subject to tighter
restrictions for power consumption on cables and optics that are used for 400 GbE ports. Reverse airflow
switches do not support high-power cables or optics. 400 GbE transceivers and active cables may exceed the
supported threshold.
●
Airflow is from the I/O panel to the PSU—the red indicator is the normal airflow direction.
●
Airflow is from the PSU to the I/O panel—the blue indicator is the reverse airflow direction.
NOTE:
Fan and PSU airflow directions must match. Do not mix normal and reverse airflows in a single switch.
Environmental factors can decrease the amount of time that is required between fan replacements. Check the environmental
factors regularly. An increase in temperature or particulate matter in the air might affect performance—for example, new
equipment installation).
