The Juniper Networks ACX5400 Universal Metro Routers are top-of-rack routers with deep packet buffer solutions for
metro network or aggregation environments. The ACX5400 router portfolio consists of high-performance,
fixed-configuration, 1-U routers that add higher port densities, additional scalability, and improved latency to the ACX
Series. The routers have a high-throughput Packet Forwarding Engine, which provides full duplex throughput of 800 Gbps.
The 1.9 Ghz six-core Intel CPU with 32 GB of memory and two 100 GB of enterprise-grade solid-state drive (SSD) storage
enhance the performance of the ACX5400 control plane.
We ship these routers with redundant fans and redundant power supply modules (PSMs). You can order the routers with
front-to-back airflow (airflow out or AFO) or back-to-front airflow (airflow in or AFI), and with AC or DC PSMs.
The ACX5400 routers are available in three variants:
•
ACX5448
•
ACX5448-D
•
ACX5448-M
ACX5448 System Overview
The ACX5448 router provides a system throughput of up to 800 Gbps through the following port configurations:
•
Forty-eight 10-Gigabit or 1-Gigabit Ethernet ports (ports 0 through 47) that support small form-factor pluggable plus
(SFP+) transceivers. These ports can also operate at 1-Gbps speed when you use 1-gigabit SFP optics.
•
Four 100-Gigabit Ethernet ports (ports 48 through 51) that support quad small form-factor pluggable 28 (QSFP28)
transceivers. You can channelize these ports into four 25-Gbps interfaces using breakout cables (and channelization
configuration). These ports also support 40-Gbps speed, when you use QSFP+ optics. You can channelize these 40-Gbps
ports into four 10-Gbps interfaces using breakout cables (and channelization configuration).
