Cisco Business CBS220-16T-2G Full English Product Description

1. Product Overview

Model Suffix Explanation

• 16: 16×10/100/1000BASE-T non-PoE copper access ports
• T: Data-only RJ45 ports without PoE power supply
• 2G: Two dedicated 1G SFP fiber uplink slots for long-distance upstream aggregation
  No "-E/D" suffix indicates standard 19-inch 1RU rack-mount chassis with integrated internal universal AC power supply, instead of desktop external adapter design. This smart switch supports intuitive HTML5 web GUI management, complete enterprise Layer 2 functions, advanced QoS and multi-layer security. It delivers wire-speed non-blocking switching for office PCs, printers, NAS storage and non-powered wireless APs, an ideal manageable network access device for SMBs with basic IT operation demands.
