MX240 Field-Replaceable Units (FRUs)
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 1 lists the FRUs for the MX240 router. Before you replace an SCB or a Routing Engine, you must take the host subsystem offline.
