This Installation Guide provides information about the Lenovo ThinkSystem
NE2572O RackSwitch (referred to as NE2572O throughout this document).
The NE2572O uses a wire ‐ speed, non ‐ blocking switching fabric that provides
simultaneous wire ‐ speed transport of multiple packets at low latency on all ports.
Port Configuration
The NE2572O contains the following ethernet ports:
 Forty ‐ eight 25 Gigabit Ethernet (GbE) Small Form Pluggable 28 (SFP28) ports
 Six 100 GbE Quad Small Form Pluggable 28 (QSFP28) ports, each of which can
optionally be used as four 10GbE SPF+ ports, or four 25GbE SPF28 ports, or two
50GbE QSPF28 ports, or one 40GbE QSPF+ port
Transceiver Configuration
QSFP+ ports can be populated with optical QSFP+ modules or passive Direct ‐ Attach
Cables (DACs), including those that allow the port to be used as four 25 GbE SFP+
ports.
Orientation, Airflow, and Redundancy
The NE2572O is 1U in height and can be mounted horizontally or vertically,
depending on your application. Mounting options are available for a variety of rack
systems.
For superior reliability, the NE2572O uses redundant, hot ‐ swap power supply
modules and six hot ‐ swap fan modules. Module options are available for
rear ‐ to ‐ front airflow.
Management
You can manage the switch through the local console port, or through a remote
network connection.
