Lenovo Flex System interconnect and pass-thru modules

A variety of network system interconnect and pass-thru modules are available for use with the Flex System Enterprise Chassis.

You can install up to four network system interconnect or pass-thru modules in the input/output (I/O) bays of the Enterprise Chassis. If you need to verify that the module is compatible with the chassis, go to the Lenovo ServerProven website.

Important: The network system interconnect and pass-thru modules in the chassis also must be compatible with the external network switches and the network adapters and ports in the nodes.

📄️ Lenovo Flex System SI4091 10Gb System Interconnect Module

The Flex System SI4091 10Gb System Interconnect Module enables simplified integration of Flex System products into your existing networking infrastructure. The SI4091 requires no management for most data center environments, so it can reduce the number of management points and eliminate the need to configure each networking device or individual port. This module provides a low latency, loop-free interface that does not rely upon spanning tree protocols, so it also eliminates one of the greatest deployment and management complexities of a traditional switch. The SI4091 offers administrators a simplified deployment experience while it maintains the performance of intra-chassis connectivity.
