MX10016 Field-Replaceable Units

Field-replaceable units (FRUs) are router components that you can replace at your site. The router uses
these types of FRUs:
Hot-insertable and hot-removable—You can remove and replace these components without powering
off the router or disrupting the routing function.
Hot-pluggable—You can remove and replace these components without powering off the router, but
the routing function is interrupted until you replace the component.
Table 7 on page 38 lists the FRUs and their types for the MX10016 routers.

Redundant configuration:
Master RCB is hot-pluggable.
Backup RCB is hot-insertable and hot-removable.
Base configuration:
Removing the RCB causes the router to shut down. You can install a replacement
Control Board in the second slot. The system restarts to elect a master and
backup. If necessary, you can switch the master and backup using the request
chassis routing-engine master switch command. We recommend that you take
the backup RCB offline before removing it.

SFBs are hot-insertable and hot-removable. We recommend that you take SFBs
offline before removing them to avoid traffic loss while the router fabric is being
reconfigured. Use the following command:
user@router> request chassis sib (offline | online) slot slot-number offline
Hot-insertable and hot-removable. We recommend that you take line cards offline
before removing them. For example:
