Ptx10000 Field-Replaceable Units; Power Supplies - Juniper PTX10008 Hardware Manual

The PTX10000 chassis houses the hardware components. The chassis components include the fan trays,
optional cable management system, and the status LED panel.

PTX10000 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 6 on page 40 lists the FRUs and their types for the PTX10000 routers.

Redundant configuration:
Master RCB is hot-pluggable.
Backup RCB is hot-insertable and hot-removable.
Base configuration:
Removal of the RCB causes the router to shut down. You can install a
replacement RCB 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.

Components and Configurations.
SIBs are hot-insertable and hot-removable. We recommend that you take SIBs
offline before removing them to avoid traffic loss while the router fabric is being
reconfigured. For example:
