Removing the System Fan from the Appliance

To remove a fan module from the SonicWall appliance:

1. Loosen the retaining thumbscrew with your fingers or a Phillips (cross) screwdriver, if necessary.
2. Noting the fan's orientation in the appliance, pull the handle all the way open until pointing straight back. This disengages the fan's contacts.
3. Wait several seconds for the fan to stop spinning.
4. Pull the fan module outwards to completely remove it from the appliance, then set it aside.

Inserting a System Fan into the Appliance

Do NOT insert anything except the Fan Module into the appliance.
To install a new fan module into the SonicWall appliance:

1. With the appliance turned off, insert the fan module into the empty slot using the same orientation you noted when you removed the defective module.
2. Push the fan module firmly into place until it is completely seated and snaps into place.
3. Return the retaining bracket across the fan module and tighten the retaining screw with a screwdriver to securely fasten the bracket.
4. Confirm that the new fan is operating correctly.
