PIC.
PICs are hot-removable and hot-insertable. A removed PIC no longer receives or
transmits data, and removing or inserting a PIC briefly interrupts forwarding of traffic
through the remaining PICs.

PIC Components

Most PICs supported on the M10i router have the following components. For complete
specifications, see the M10i Internet Router PIC Guide. For information about pinouts

Compact Forwarding Engine Board (CFEB)

The Compact Forwarding Engine Board (CFEB) performs route lookup, filtering, and
switching on incoming data packets, then directs outbound packets to the appropriate
FPC for transmission to the network. It can process 16 million packets per second
(Mpps).
One or two CFEBs can be installed into the midplane from the rear of the chassis,
as shown in
is in standby mode. By default, the CFEB in slot
default, include the appropriate
hierarchy level of the configuration, as described in the section about CFEB
redundancy in the JUNOS System Basics Configuration Guide.
CFEBs are hot-pluggable, as described in
Removing the standby CFEB has no effect on router function. If the active CFEB fails
or is removed from the chassis, the effect depends on how many CFEBs are installed:
on page 19). The number of ports on a PIC depends on the type of
One or more cable connector ports—Accept a network media connector.
LEDs—Indicate PIC and port status. Most PICs have an LED labeled
the PIC faceplate. Some PICs have additional LEDs, often one per port. The
meaning of the LED states differs for various PICs. For more information, see
the M10i Internet Router PIC Guide.
Ejector lever—Controls the locking system that secures the PIC in the card cage.

If there is one CFEB, forwarding halts until the CFEB is replaced and functioning
again. It takes approximately one minute for the replaced CFEB to boot and
become active; reading in router configuration information can take additional
time, depending on the complexity of the configuration.
If there are two CFEBs, forwarding halts while the standby CFEB boots and
becomes active, which takes approximately one minute; synchronizing router
configuration information can take additional time, depending on the complexity
of the configuration.
