MX960 3D Universal Edge Router Hardware Guide
Several types of DPCs are available. Each DPC includes either two or four Packet
Forwarding Engines. Each Packet Forwarding Engine enables a throughput of 10 Gbps.
Up to two PICs can be installed in each FPC. Fully populated, the MX960 supports up to
12 PICs.
Up to two Modular Interface Cards (MICs) can be installed in each MPC. Fully populated,
the MX960 supports up to 24 MICs.
MPCs support fixed interfaces or up to two Modular Interface Cards (MICs) that can be
installed in each MPC. Fully populated, the MX960 supports up to 22 MICs.
For a list of the supported DPCs, FPCs, MPCs, MICs, and PICs, see the
Module Reference
Three SCBs are available for the MX960 routers—the SCB, the SCBE, and the SCBE2.

Description
Enhanced MX Switch Control Board (SCBE2)
Enhanced Switch Control Board (SCBE)
Switch Control Board (SCB)
Switch fabric—Connects the interface cards and provides for packet transport between
DPCs, FPCs, and MPCs. Two SCBs provide one nonredundant fabric. Three SCBS are
required for a redundant fabric configuration.
Control Plane—Gigabit Ethernet links between the combined SCBs/Routing Engines
and each DPC, FPC, or MPC. All board-to-board information is passed over Ethernet
except for low-level status and commands.
Management signals—Provide low-level status diagnostic support.
