    Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing FRUs requires minimal router downtime. There are three types of FRUs:

    • Hot-removable and hot-insertable—You can remove and replace the component without powering down the router or interrupting the routing functions.
    • Hot-pluggable—You can remove the component without powering down the router, but routing functions are interrupted until the replacement is installed.
    • Requires router shutdown—You must power down the router before removing the component.
