#### External and Internal Faults

When a system component experiences a hardware failure, it is called an internal fault. The fault is the result of a problem with the hardware of the modular system itself.

Internal faults are cleared when a repair action takes place, most likely the replacement of the failed component.

With external faults, there is no failed system hardware. A condition that is outside the system is causing a potential problem. For example, if the ambient air temperature (external to the chassis) exceeds a certain threshold, it is a fault. The heat can adversely affect the system if the temperature is not reduced. External faults are auto-clearing.

External faults are cleared when the external condition no longer exists. Nonetheless, an external fault can cause components or the system as a whole to shut down if the problem is not resolved.
