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.
Midplane connectors and power circuitry.
Processor subsystem, which includes a 1.5-GHz CPU, system controller, and 1 GB of SDRAM.
Online button which takes the MPC online or offline when pressed.
OK/Fail LED on the MPC faceplate. For more information about LEDs on the MPC faceplate, see the
