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
MX Series Interface Module Reference
Two LEDs, located on the craft interface above the MPC, display the status of the line
cards and are labeled and
OK
