Page 6: Introduction
Introduction Introduction This document illustrates how to configure Dell EMC™ Networking S4048-ON switches for use with Dell™ PS Series storage while using Dell EMC best practices. The recommended configuration uses Link Aggregation Groups (LAGs) for inter-switch connections. The host servers and storage controllers can be connected to the switches using the 40GbE Quad Small Form-factor Pluggable (QSFP) ports with appropriate breakout cables. -

Note: Firmware downloads and documentation can be found at Dell.com/support. Dell EMC recommended switch configuration The steps in this section show how to configure two S4048-ON switches with a Link Aggregation Group (LAG). The switches are interconnected using two of the 40GbE Quad Small Form-factor Pluggable (QSFP) uplink ports, and the LAG is configured for Dynamic Link Aggregation Control Protocol (LACP). -
