None.Fan modules
NOTE: If you have a Juniper Networks J-Care service contract, register any
addition, change, or upgrade of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp .
Failure to do so can result in significant delays if you need replacement parts.
This note does not apply if you replace existing components with the same
type of component.

Understanding Redundancy of QFX3100 Director Device Components and Functionality
The QFX3100 Director device is designed to provide redundancy in platforms and
components to minimize the possibility that a single point of failure can cause an entire
QFX3000 QFabric system to fail.
Two QFX3100 Director devices are connected together in a QFX3100 Director group to
provide control plane and management network redundancy for a QFX3000 QFabric
system.
The hardware components of a single QFX3100 Director device are also designed for
redundancy to minimize the possibility that a single point of failure causes a Director
device to fail.

QFX3100 Director Device Redundancy
Two QFX3100 Director devices are connected together in a QFX3100 Director group to
provide control plane and management network redundancy for a QFX3000 QFabric
system. When one QFX3100 Director device fails, the second QFX3100 Director device
in the QFX3100 Director group continues to operate with minimal network disruption.
