Midplane connectors and power circuitry.
Processor subsystem, which includes a 1.2-GHz CPU, system controller, and 1 GB of SDRAM.
Online button—Takes the DPC online or offline when pressed.
LEDs on the DPC faceplate. For more information about LEDs on the DPC faceplate, see the
Interface Module Reference.
Two LEDs, located on the craft interface above the DPC, display the status of the DPC and are labeled
OK and FAIL.

MX240 DPC Port and Interface Numbering

Each port on a DPC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (-) separates the media type from the DPC number (represented
as an FPC in the CLI). The DPC slot number corresponds to the first number in the interface. The second
number in the interface corresponds to the logical PIC number. The last number in the interface matches
the port number on the DPC. Slashes (/) separate the DPC number from the logical PIC number and port
number.
type-fpc/pic/port
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—Slot in which the DPC is installed. On the MX240 router, the DPCs are represented in the CLI as
FPC 0 through FPC 2.
pic—Logical PIC on the DPC. The number of logical PICs varies depending on the type of DPC. For
example, a:
20-port Gigabit Ethernet DPC has two logical PICs, numbered 0 through 1.
40-port Gigabit Ethernet DPC has four logical PICs, numbered 0 through 3.
