Lenovo ThinkSystem NE2572 RackSwitch
Product Guide
The Lenovo ThinkSystem NE2572 RackSwitch is designed for the data center and provides
10 Gb/25 Gb Ethernet connectivity with 40 Gb/100 Gb Ethernet upstream links. It is ideal for big data,
cloud, and enterprise workload solutions. It is an enterprise class Layer 2 and Layer 3 full featured switch
that delivers line-rate, high-bandwidth switching, filtering, and traffic queuing without delaying data. Large
data center-grade buffers help keep traffic moving, while the hot-swap redundant power supplies and fans
(along with numerous high-availability software features) help provide high availability for business sensitive
traffic.
The NE2572 RackSwitch has 48x SFP28/SFP+ ports that support 10 GbE SFP+ and 25 GbE SFP28
optical transceivers, active optical cables (AOCs), and direct attach copper (DAC) cables. The switch also
offers 6x QSFP28/QSFP+ ports that support 40 GbE QSFP+ and 100 GbE QSFP28 optical transceivers,
active optical cables (AOCs), and direct attach copper (DAC) cables. The QSFP28/QSFP+ ports can also
be split out into four 10 GbE (for 40 GbE QSFP+) or 25 GbE (for 100 GbE QSFP28) connections by
using breakout cables.
The NE2572 RackSwitch is ideal for latency sensitive applications, such as high-performance computing
clusters and financial applications.

Did you know?
With exceptional port density and flexibility with break-out cables, the NE2572 RackSwitch can support up
to 72x 10 GbE / 25 GbE Ethernet connections or a mix of 10 GbE / 25 GbE server and storage connections
with 40 GbE or 100 GbE upstream network connections in a 1U rack form factor.
The NE2572 RackSwitch runs the Cloud Networking Operating System (CNOS) that provides a simple,
open and programmable network infrastructure with cloud-scale performance. It delivers a software-
defined Ethernet solution that is simple to manage and easy to deploy using common management tools,
and it enables support of automation and orchestration applications for tight integration into the data
center ecosystem.
