transmitting outgoing data packets, the PICs encapsulate the packets received from the
FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the
media type of that PIC.
PICs are hot-removable and hot-insertable. Up to two PICs can be installed in the slots
in each FPC. Up to three FPCs can be installed in an MX480 router. PICs used in a Type
2 FPC have captive screws at their upper and lower corners. PICs used in a Type 3 FPC
have an upper ejector handle and a lower captive screw.

Each port on a PIC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (
number (represented as an
number in the interface. The second number in the interface corresponds to the PIC
number. The last number in the interface matches the port number on the PIC. Slashes

type—Media type, which identifies the network device. For example:
ge—Gigabit Ethernet interface
so—SONET/SDH interface
xe—10-Gigabit Ethernet interface
For a complete list of media types, see Interface Naming Overview.
fpc—Lowest slot number in which the FPC is installed. On the MX480 router, FPCs
occupy two line card slots and are represented in the CLI as
pic—PIC number, 0 or 1 depending on the FPC slot.

port—Port number.
The MX480 supports up to three FPCs that install horizontally and are numbered from
bottom to top.
