Mpc Components; Mx480 Modular Port Concentrator (Mpc) Leds - Juniper MX480 Hardware Manual

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
Two LEDs, located on the craft interface above the MPC, display the status of the line cards and are labeled
OK and FAIL.

MX480 Modular Port Concentrator (MPC) LEDs

Two LEDs, located on the craft interface above the MPC, display the status of the line cards and are labeled
OK and FAIL. For more information about the line card LEDs on the craft interface, see
