A Dense Port Concentrator (DPC) is optimized for Ethernet density (see
page 11). The DPC assembly combines packet forwarding and Ethernet interfaces on a
single board, with either two or four 10-Gbps Packet Forwarding Engines. Each Packet
Forwarding Engine consists of one I-chip for Layer 3 processing and one Layer 2 network
processor. The DPCs interface with the power supplies and Switch Control Boards (SCBs).
The DPC slots are located in the front of the router (see
has six dedicated DPC slots that are numbered
any DPC slot on the router. You can install any combination of DPC types in the router.
If a slot is not occupied by a DPC, a DPC blank panel must be installed to shield the empty
slot and to allow cooling air to circulate properly through the router.
