FAQs

Q: Is this fan compatible with the 8540 Wireless Controller?
A: Yes. The 8540 Wireless Controller is based on the UCS C240 M4 chassis, and this fan is designed for that platform.

Q: Do I need to power down the controller to replace this fan?
A: If the chassis has sufficient fan redundancy, the module can be hot-swapped. Follow site change-control and chassis documentation.

Q: How many fans are required for full redundancy?
A: Refer to the UCS C240 M4 chassis guidelines for minimum and fully populated fan configurations to achieve N+1 redundancy.
