Mx480 Hardware Overview - Juniper MX480 Hardware Manual

Junos Telemetry Interface—Using the Junos telemetry interface data, you can stream component-level
data to monitor, analyze, and enhance the performance of the network. Analytics derived from this
streaming telemetry can identify current and trending congestion, resource utilization, traffic volume,
and buffer occupancy.
Integrated Hardware-Based Timing—You do not need to use external clocks because MX Series routers
support highly scalable and reliable hardware-based timing, including Synchronous Ethernet for frequency,
and the Precision Time Protocol (PTP) for frequency and phase synchronization. Synchronous Ethernet
and PTP can be combined in a hybrid mode to achieve a high level of frequency (10 ppb) and phase (<1.5
uS) accuracy.

MX480 Hardware Overview

The MX480 chassis provides redundancy and resiliency. The hardware system is fully redundant, including
power supplies, Routing Engines, and Switch Control Boards (SCBs).
The MX480 router is eight rack units (U) tall. Five routers can be stacked in a single floor-to-ceiling rack,
for increased port density per unit of floor space. The router provides eight slots that can be populated
with up to six Dense Port Concentrators (DPCs) or Modular Port Concentrators (MPCs), three Flexible PIC
Concentrators (FPCs), and two SCBs. Each FPC holds up to two PICs and each MPC holds up to two
Modular Interface Cards (MICs).
Fully populated, the MX480 router provides an aggregate switch fabric capacity of up to 5.76 Tbps and
line-rate throughput for up to 240 10-Gigabit Ethernet ports, or 24 100-Gigabit Ethernet, or 72 40-Gigabit
Ethernet ports.
Table 3 on page 28 lists the MX480 router capacity.

Each DPC includes either two or four Packet Forwarding Engines. Each Packet Forwarding Engine enables
a throughput of 10 Gbps. Many types of DPCs are available. For a list of the DPCs supported, see the
