Lenovo Flex System EN4023 10Gb Scalable Switch

The Lenovo Flex System EN4023 10Gb Scalable Switch is a high-density, 64-port, 10-Gbps
Ethernet switch that is used in the Lenovo Flex System chassis. The switch provides 42 internal
ports to compute nodes by way of the midplane, and 14 external SFP+ ports that are capable of
running 10-Gbps Ethernet and 4-Gbps, 8-Gbps, and 16-Gbps Fibre Channel. Also included are two
external Quad SFP (QSFP) ports that can support 40-Gbps Ethernet or 4x10-Gbps Ethernet in
breakout mode.

This

User’s Guide
