A computer network may include one or more systems coupled to many components. The computer network may be a storage network that includes one or more systems connected to one or more storage systems. One or more components coupled to the computer network may be modular components such as field replaceable units (FRUs). A component may include a non-volatile memory that stores a value for an operational parameter of the component. The value for the operational parameter may specify an operating condition for the component. A monitor may be coupled to the component and may be configured to access the operational parameter value on the nonvolatile memory to determine if the component is operating outside of the specified operating condition.
