eSmartES™ ES7028G Series


The ES7028G Series of Managed Ethernet Switches are high port density switches offering flexible designs for field upgradable expansion. All models include Westell’s industry-leading SiteVu™ Secure telemetry feature, and optional (on ESP model) Power over Ethernet (PoE) and PoE+, as well as four gigabit ports that are UTP/SFP combinations. The ES7028G model is modular and field upgradable, allowing the user to quickly and easily add option modules to the 12-port base unit, resulting in a switch with options for 12, 14, 16, 20, 22 or 28 ports.


8-port FE Module
