Dell EMC PowerSwitch S5048F-ON Installation Guide December 2019

Fans

The S5048F-ON switch comes from the factory with two PSUs and four fan modules that are installed in the switch. The fan modules and the power supplies, which have integrated fans, are hot-swappable.

You can order and install fan modules separately.

The S5048F-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 particulate matter in the air might affect performance—for example, new equipment installation).
