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 (CBs).
The router has 11 dedicated DPC slots. DPCs install vertically in the front of the router
(see Figure 21 on page 55). The dedicated DPC slots are numbered
though , left to right. An additional multifunction slot labeled

SCB or a DPC. A DPC can be installed in any slot that supports DPCs. 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. 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.
