As Mlc Components; Mx480 Scb, Power Supply, And Cooling System Requirements For As Mlc - Juniper MX480 Hardware Manual

AS MLC Components

Each AS MLC consists of the following components:
AS MLC Modular Carrier Card (AS MCC), which fits horizontally in front of the MX480 router, includes
two slots for the Application Services Modular Storage Card (AS MSC) and Application Services Modular
Processing Card (AS MXC)
AS MXC with 64 GB RAM for processing
AS MSC with 400 GB of NAND Flash capacity for modular storage
NOTE: The AS MCC, AS MXC, and AS MSC are hot-removable and hot-insertable.
Switch fabric interfaces to the chassis
XM ASIC chip, which owns and manages the packet data memory built from external DDR3 memory
chips, the fabric queuing system, a portion of the WAN queuing system, and the host queuing system
LU ASIC chip, which performs all functions relating to header processing including input processing,
route lookup, classification, filtering, policing, accounting, encapsulation, and statistics
Midplane connectors and power circuitry
Processor Mezzanine Board (PMB), which contains the host processor and supporting peripherals.
