Replacing a fan assembly
Attention: Before installing, removing, or replacing any component, read and
follow the “Safety notices and labels” on page xv.
Use this procedure to remove and replace a fan assembly in the router. The router
can continue operating during the replacement procedure if the other fan
assemblies continue to operate and the replacement is completed within 2 minutes.
This will ensure correct air pressure inside the chassis for the router cooling
requirements.
Attention: The fans in the fan assembly will continue to spin after they are
removed from power. Wait approximately five seconds after disengaging a fan
assembly from the chassis before removing it entirely from the chassis. This will
allow the spinning fan blades to slow or stop completely.
The router has three fan assembly slots, and each fan assembly contains two fans.
The fan assemblies are interchangeable and can be inserted into any of the fan
assembly slots (see Figure 12).
