Field-replaceable units (FRUs) are router components that can be replaced at the
customer site. Replacing FRUs requires minimal router downtime. There are three types
of FRUs:
Hot-removable and hot-insertable—You can remove and replace the component
without powering down the router or interrupting the routing functions.
Hot-pluggable—You can remove the component without powering down the router,
but routing functions are interrupted until the replacement is installed.
Requires router shutdown—You must power down the router before removing the
component.

The M10i router provides high-speed interfaces for medium and large networks and
network applications, such as those supported by Internet service providers (ISPs). (See
Figure 3 on page 8.)
The M10i router includes the router-specific Compact Forwarding Engine Board (CFEB)
which performs route lookup, filtering, and switching on incoming data packets, then
directs outbound packets to the appropriate Flexible PIC Concentrator (FPC) for
transmission to the network. It can process 16 million packets per second (Mpps).
A High-Availability Chassis Manager (HCM) works with its companion Routing Engine to
provide control and monitoring functions for router components. The HCM also displays
alarm status and takes PICs online and offline.
On the M10i router, built-in FPCs house the PICs that connect the router to network media.
The router supports up to eight PICs, including ATM, Channelized, Gigabit Ethernet, IP
Services, and SONET/SDH interfaces. For more information on PICs, see the M10i
Multiservice Edge Router PIC Guide .
