DPCs are hot-removable and hot-insertable, as described in “MX480 Field-Replaceable
Units (FRUs)” on page 161. 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 5 on page 11 shows typical DPCs supported on the MX480 router. For more
information about DPCs, see the MX Series 3D Universal Edge Routers Line Card Guide.
