The Z9100–ON comes from the factory with two PSUs and five fan modules installed in the switch. The fan modules and PSUs,
which have integrated fans, are hot-swappable.
In addition to the power supply modules, you can order and install fan modules separately. The Z9100-ON requires a minimum of
four running fans.
The Z9100-ON supports two airflow direction options. Do not mix airflow types in a switch; you can use only a single airflow
direction in a switch. All fans and PSUs in a configuration must be in the same airflow direction.
● Normal—airflow is from the I/O side to the PSU side.
● Reversed—airflow is from the PSU to the I/O side.
Environmental factors can decrease the amount of time needed between fan replacements. Check the environmental factors
regularly. An increase in temperature and particulate matter in the air might affect performance; for example, new equipment
installation.
CAUTION:
Check the fans at six-month intervals, and replace them as necessary. Regularly monitor the speeds
of the fans to accurately determine replacement intervals.
