ACX5000 Universal Access Router Overview
The ACX5000 Universal AccessRouters are Juniper Networks’ top-of-rack router solutions
for data centers and campus distribution or aggregation environments. The ACX5000
router portfolio consists of high-performance fixed-configuration routers that add higher
port densities, additional scalability, and improved latency to the ACX Series. The
ACX5000 routers are available in two models—ACX5048 and ACX5096. See “ACX5000
Router Models” on page 5.
ACX5000 routers offer a compact 1 U model and a 2 U model that provide wire-speed
packet performance, very low latency, and a rich set of Layer 2 and Layer 3 features.
These routers have a high-throughput Packet Forwarding Engine, and the performance
of the control plane running on ACX5000 routers is enhanced by the 1.5 Ghz dual-core
Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.
The ACX5000 routers include both 10-Gigabit Ethernet and 40-Gigabit Ethernet fixed
configurations.
The ACX5000 router consists of:

As shown in Figure 1 on page 4, the ACX5048 is a 10-Gigabit Ethernet enhanced small
form-factor pluggable (SFP+) top-of-rack router with 48 SFP+ ports and 6 quad SFP+
