(FPCs) on other M Series routers. The FEB contains the Internet Processor II
application-specific integrated circuit (ASIC), two distributed Buffer Manager ASICs, and
two I/O Manager ASICs, and is responsible for making forwarding decisions, distributing
packets throughout memory, and forwarding notification of outgoing packets.
The M5 and M10 routers provide a wide range of high-performance interfaces from T1
and E1 through OC12c/STM4 (for the M5 router) or OC48c/STM16 (for the M10 router).
PICs between the two routers are interchangeable. For more information about supported
PICs and FPCs for each M Series router type, see the appropriate PIC installation guide.
The M5 and M10 router Internet processor II ASIC forwards packets at a throughput rate
of up to 5 Gbps for the M5 router and up to 10 plus Gbps for the M10 router. The ASIC
technology provides such packet processing as rate limiting, filtering, and sampling of
IP services.

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.
