Juniper Networks MX480 - Manual (Page 39)

• 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 3D Universal Edge Routers Line Card Guide .
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 “DPC and MPC LEDs on the MX480 Craft Interface” on page 39 .
Each MPC also has LEDs located on the faceplate. For more information about LEDs on
the MPC faceplate, see the “LEDs” section for each MPC in the
MX Series 3D Universal
Edge Routers Line Card Guide .

MX480 Modular Interface Card (MIC) Description
Modular Interface Cards (MICs) install into Modular Port Concentrators (MPCs) and
provide the physical connections to various network media types. MICs allow different
physical interfaces to be supported on a single line card. You can install MICs of different
media types on the MPC as long as the MPC supports those MICs.
