4 With both hands, pull out the ejector levers of the fan that will be installed. Align
it with the guides in the chassis and slide it gently into the slot until you feel the
positioning pin on the handle bar touch the hole in the chassis.
5 Press the ejector levers inward and seat the pin on the handle bar into the
positioning hole in the chassis.
WARNING: If the fan fails, replace it with a new one without delay before
operating the Switch 7700. Failure to do so will cause the switch to overheat.
