DPC Components
Each DPC consists of the following components:
• DPC cover, which functions as a ground plane and a stiffener.
• Fabric interfaces.
• Two Gigabit Ethernet interfaces that allow control information, route information, and
statistics to be sent between the Routing Engine and the CPU on the DPCs.
• Two interfaces from the SCBs that enable the DPCs to be powered on and controlled.
• Physical DPC connectors.
• Two or four Packet Forwarding Engines.
• 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
MX Series 3D Universal Edge Routers Line Card Guide .
Two LEDs, located on the craft interface above the DPC, display the status of the DPC
and are labeled
OK and FAIL .

MX480 Dense Port Concentrator (DPC) LEDs
Two LEDs, located on the craft interface above the DPC, display the status of the DPC
and are labeled
OK and FAIL . For more information about the DPC LEDs on the craft
interface, see “DPC and MPC LEDs on the MX480 Craft Interface” on page 39 .
Each DPC also has LEDs located on the faceplate. For more information about LEDs on
the DPC faceplate, see the “LEDs” section for each DPC in the
