Field-replaceable units (FRUs) are router components that can be replaced at the
customer site. Replacing most FRUs requires minimal router downtime. The router uses
the following types of FRUs:
Hot-removable and hot-insertable FRUs—You can remove and replace these
components without powering off the router or disrupting the routing functions.
Hot-pluggable FRUs—You can remove and replace these components without powering
down the router, but the routing functions of the system are interrupted when the
component is removed.
Before you replace a CB or a Routing Engine, you must take the host subsystem offline.
Table 75 on page 186 lists the FRUs for the M320 router.
