Fans
The N2200-ON Series switch comes from the factory with two or three pluggable fan modules.
● N2224X-ON and N2224PX-ON—Two fan modules
● N2248X-ON and N2248PX-ON—Three fan modules
The N2224X-ON and N2248X-ON switches support 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 on the handle is the normal airflow direction.
● Airflow is from the PSU to the I/O panel—the blue indicator on the handle is the reverse airflow direction.
NOTE: Reverse airflow is only supported on the N2224X-ON and N2248X-ON AC switches.
All fans and PSUs in a configuration must be in the same airflow direction.
Environmental factors can decrease the amount of time that is 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.
