Flexible PIC Concentrators (FPCs) house the PICs that connect the router to network
media (for information about PICs, see "M7i PICs Description" on page 16). On the M7i
router, each FPC is built in (it cannot be removed from the chassis as on other M Series
routers). The networking and services interfaces in the M7i router are grouped onto two
logical FPCs by the router, (see Figure 11 on page 18). PICs are located on

The Routing Engine runs Junos OS. The software processes that run on the Routing Engine
maintain the routing tables, manage the routing protocols used on the router, control
the router's interfaces, control some chassis components, and provide the interface for
system management and user access to the router.
The Routing Engine is installed into the midplane from the front of the chassis, as shown
in Figure 1 on page 6. When two Routing Engines are installed, both are powered on, but
only one is active (the master); the second Routing Engine is in standby mode and
performs no functions. At boot time, both Routing Engines run an arbitration algorithm
and elect one as master. For a more detailed description of the Routing Engine's role in
router architecture, see "Routing Engine Architecture" on page 29.
The Routing Engine is hot-pluggable. If you have only one Routing Engine, you can remove
and replace the Routing Engine without powering down the router, but the routing
functions of the system are interrupted when it is removed. If the host system is redundant,
the backup Routing Engine is hot-removable and hot-insertable. A backup Routing Engine
can be removed without interrupting routing functions.
