MPC
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.
