Fans
The fans are hot pluggable. This means you can remove or install one of the fans while the switch is operating without disrupting service. The fan is completely enclosed, so there is no risk of injury from the fan blades. The fans are also interchangeable; that is, the left and right fans are the same unit.
To remove a fan, loosen the two retaining screws, then grasp the fan housing and pull firmly to disengage the modular connector. Slide the fan out of its bay as shown in Figure

A label on the fan indicates the switch model number and fan air flow direction as shown in Figure
CAUTION! Both fans must have the same air flow direction to prevent the switch from overheating.
