Reverse airflow fan for Dell switches

This replacement fan moves air from the power-supply side toward the I/O side in compatible Dell network switches. It is a direct-fit spare for the X3WCP assembly used in specific S-series and Z-series platforms.

Suits technicians maintaining listed Dell switches

It fits only the S4248FB-ON, S4248FBL-ON, S5048F-ON, S5148F-ON and Z9100-ON models. Operators of other Dell switches, different brands or standard server chassis should source the correct part for their hardware.

Reverse PSU-to-I/O airflow direction

The unit pulls cool air through the power supplies and exhausts it out the I/O panel, matching the original thermal design. Installing a fan with the opposite flow would disrupt cooling in these switches.
