The Z9264F-ON switch comes from the factory with two PSUs and four fan modules installed in the switch. 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 Z9264F-ON switch supports two airflow direction options. 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.
•
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.
All fans and PSUs in a configuration must be in the same airflow direction.
Environmental factors can decrease the amount of time required between fan replacements. Check the environmental factors regularly. An
increase in temperature and/or 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.
