Chapter 7: Fans; Components - Dell EMC PowerSwitch Z9100–ON Installation Manual

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.
