Step 3: Pull the entire fan module out after it completely stops rotating.

Caution:

zThe fan module is rather long. Use one hand to hold the bottom of the fan while the other hand grasps the handle on the fan and pull it out slowly.

zEven though you have disconnected the fan module from power supply when pulling it out, it may still rotate for a while for inertia sake. Be careful and do not put your finger into the rotating fans.

6.3.2Installing the Fan Module

Step 1: Hold the handle on the fan module with one hand and the bottom with the other hand. Slowly insert the fan module into the chassis along the guides until it well touches the backplane.

Step 2: Fasten the captive screws on the fan module.

Step 3: Power on the router and check that the FAN LED is solid ON.
