MX104 Field-Replaceable Units (FRUs) on page 135
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 73 on page 135 lists the FRUs for the MX104 router. Before you replace a Routing
Engine, you must take the Routing Engine offline.
