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.
FRUs that require powering off the router—You must power off the router before
removing these components.
Table 21 on page 158 lists the FRUs for the M40e router.
