MPC Components

Each MPC consists of the following components:
MIC 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.
Up to four Junos Trio chipsets, which perform control functions tailored to the MPC's
media type.
Backplane connectors and power circuitry.
Online button located on the craft interface, 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
