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.
