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.
