A Dense Port Concentrator (DPC) is optimized for Ethernet density (see
Figure 27 on page 91). 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.
DPCs are hot-removable and hot-insertable, as described in
Units (FRUs)" on page 226. When you install a DPC in an operating router, the Routing
Engine downloads the DPC software, the DPC runs its diagnostics, and the Packet
Forwarding Engines housed on the DPC are enabled. Forwarding on other DPCs continues
uninterrupted during this process.
Figure 27 on page 91 shows typical DPCs supported on the MX480 router. For more
