S4100–ON Series S4128F-ON, S4148F-ON, and S4148FE Installation Guide November 2017

PDF

Fans

The S4100–ON Series (S4128F-ON, S4148F-ON, and S4148FE-ON) switch comes from the factory with two PSUs and four fan modules installed in the chassis. The fan modules and the power supplies are hot-swappable.

In addition to the power supply modules, you can order and install fan modules separately.

  • NOTE: The S4100–ON Series switch supports two airflow direction options—normal and reverse. All fans and PSUs MUST have the same airflow direction. If you mix the airflow direction, to avoid heat damage to the switch components, you must correct the mixed airflow direction.
  • Airflow is from the I/O panel to the PSU—normal.
  • Airflow is from the PSU to the I/O panel—reverse.

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.
