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.
