Dense Port Concentrators (DPCs)
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.
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 4-port 10-Gigabit Ethernet faceplate, which indicate the port status.
LEDs are labeled top to bottom
LEDs on a 40-port Gigabit Ethernet faceplate indicate the port status. LEDs are
