40-Port Gigabit Ethernet Enhanced Queuing Ethernet Services DPC with SFP A DPC provides multiple physical interfaces and Packet Forwarding Engines on a single board that installs into a slot within the MX240, MX480, and MX960 3D Universal Edge Routers. A DPC receives incoming packets from the network and sends outgoing packets to the network. The Packet Forwarding Engines on a DPC are equipped with purpose-built ASICs that perform packet processing and forwarding.

When a slot is not occupied by a DPC, you must insert a blank DPC to fill the empty slot and ensure proper cooling of the system. For complete information about installing and handling DPCs, see the hardware guide for your router.
