Some PICs, such as Gigabit Ethernet PICs, accept small form-factor pluggable tranceivers
(SFPs), which are fiber-optic transceivers that can be removed from the PIC.
The M10i router provides a maximum aggregate throughput of 12.8 gigabits per second
(Gbps). Control operations in the router are performed by the Routing Engine, which runs
Junos OS to handle routing protocols, traffic engineering, policy, policing, monitoring, and
configuration management. Forwarding operations in the router are performed by the
Packet Forwarding Engine.

Table 5 on page 9 lists the major M10i router components and characteristics.
Quantity Function
1 or 2 Provides route lookup, filtering, and
switching on incoming data packets;
directs outbound packets to the
appropriate FPC for transmission to the
network
2 fan Cools router components
trays (8
fans)
2 House the PICs that connect the router to
network media
2 Works with a companion Routing Engine
to provide control and monitoring
functions for router components; displays
alarm status; takes PICs online and offline
1–8 Provides interfaces to various network
media; receives incoming packets from the
network and transmits outgoing packets
to the network, performing framing and
line-speed signaling for their media type;
encapsulates outgoing packets received
from the FPCs before transmitting them.
1–4 Distributes needed voltages to
AC or DC components
Fiber-optic transceivers that connect to
PICs
