Objective

The Cisco SG350-28P 28-Port Gigabit Power over Ethernet (PoE)Managed Switch is a standalone switch that provides 24/28 ports of Gigabit Ethernet and 4/28 (2 SFP + 2 Combo) Gigabit Ethernet ports. It comes with a new generation, highly-integrated packet processor for Carrier Ethernet and Small-Medium Enterprise (SME) applications with full wire-speed performance.

This article aims to show the features of the SG350-28P 28-Port Gigabit PoE Managed Switch.
