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 100 on page 264

lists the FRUs for the MX960 router. Before you replace an SCB or

a Routing Engine, you must take the host subsystem offline.
