M10i 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 down 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 1 lists the FRUs for the M10i router.
