Flex System EN2092 1Gb Ethernet Scalable Switch 7Simplified managementA key challenge is the management of a discrete network environment. The EN2092 1Gb ScalableSwitch supports a command-line interface (CLI) for integration into existing scripting and automation.Network management can be simplified by using port profiles, topology views, and virtualizationmanagement.For more advanced levels of management and control, which can significantly reduce deploymentand day-to-day maintenance times, while providing in-depth visibility into the network performanceand operations of Lenovo switches. Plus, when leveraging tools like VMware vCenter Server orvSphere, or Switch Center provides additional integration for better optimization.Features and specificationsNote: Features and specifications listed in this section are based on Networking OS 7.8.The EN2092 Scalable Switch has the following features and specifications:Internal portsTwenty-eight internal full-duplex Gigabit portsTwo internal full-duplex 1 GbE ports connected to the chassis management moduleExternal portsFour ports for 1 Gb or 10 Gb Ethernet SFP/SFP+ transceivers (support for 1000BASE-SX,1000BASE-LX, 1000BASE-T, 10GBASE-SR, or 10GBASE-LR) or SFP+ direct-attach copper(DAC) cables.
