MPC Components
Each MPC consists of the following components:
MPC card carrier, which includes two MIC slots (excludes the fixed configuration MPC).
Fabric interfaces.
Two Gigabit Ethernet interfaces that allow control information, route information, and statistics to be
sent between the Routing Engine and the CPU on the MPCs.
Two interfaces from the SCBs that enable the MPCs to be powered on and controlled.
Physical MPC connectors.
Up to four Junos Trio chipsets, which perform control functions tailored to the MPC's media type.
