Field-replaceable units (FRUs) are TX Matrix Plus components that can be replaced at
the customer site. Replacing most FRUs requires minimal TX Matrix Plus router downtime.
The TX Matrix Plus router uses the following types of FRUs:
Hot-removable and hot-insertable FRUs—You can remove and replace these
components without powering down the TX Matrix Plus router or disrupting the routing
functions.
Hot-pluggable FRUs—You can remove and replace these components without powering
down the TX Matrix Plus router, but the routing functions of the system are interrupted
when the component is removed.
Table 54 on page 324 lists the FRUs for the TX Matrix Plus router.
