Juniper MX480 Hardware Manual page 28

The MX480 supports up to 3 FPCs containing up to 6 PICs or up to 6 MPCs containing up to 12 MICs.
For a list of the supported line cards, see the
Four SCBs are available for the MX480 routers—SCB, SCBE, SCBE2, and SCBE3.
Table 4 on page 29 compares the fabric bandwidth capacities of SCBs per MX-series router.

Description Fabric Bandwidth Per Slot
Enhanced MX Switch Up to 1.5 Tbps (non-redundant
Control Board (model fabric configuration with
SCBE3-MX) MPC10E line cards); 1 Tbps
(redundant fabric configuration
with MPC10E line cards)
Enhanced MX Switch Up to 480 Gbps
Control Board (non-redundant fabric
(SCBE2-MX) configuration); 340 Gbps
(redundant fabric configuration)
Enhanced MX Switch Up to 240 Gbps
Control Board (non-redundant fabric
(SCBE-MX) configuration); 160 Gbps
(redundant fabric configuration)
Switch Control Board Up to 240 Gbps
(SCB-MX) (non-redundant fabric
configuration); 120 Gbps
(redundant fabric configuration)
The connections between DPCs, FPCs, MPCs, and SCBs are organized in three groups:
Switch fabric—Connects the interface cards and provides for packet transport between DPCs, FPCs,
and MPCs.
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 for low-level status diagnostic support.
