MX10003 Field-Replaceable Units

Field-replaceable units (FRUs) are router components that can be replaced at the customer site (see
Table 7 on page 24). 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 7 on page 24 lists the FRUs for the router.
