Installing and Removing a Fan Module
The fan module is field-replaceable and hot-swappable. Hot-swapping allows you to replace the fan

1. Remove the old fan module.
a. Using a Phillips Head screwdriver, turn the screw counter-clockwise until loose (it cannot be
removed completely).
b. Use the fan module handle to pull the fan module out.
2. Align the new fan module with opening in the gateway.
3. Insert the fan module into the gateway (see Figure 11 ).
4. Tighten the screw on the fan module to secure it.
