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
off the router, but the routing functions of the system are interrupted when the
component is removed.
Table 95 on page 226 lists the FRUs for the MX960 router. Before you replace an SCB or
a Routing Engine, you must take the host subsystem offline.
