Fans
The Z9100–ON comes from the factory with two PSUs and five fan modules installed in the chassis. The fan modules and the power
supplies, 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 supports two airflow direction options. Do not mix airflow types in a chassis; you can use only a single airflow direction in a
chassis. All fans and PSUs in a configuration must be in the same airflow direction.
•
Normal—airflow is from the I/O panel to the PSU.
•
Reversed—airflow is from the PSU to the I/O panel.
Environmental factors can decrease the amount of time required 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.
