L2+ Managed Switch

Product Name

24+4 L2+switch

Model

GS2220-28

Introduction

Integrate the advanced protection function of HERHSIANG NGS series firewall, it can become an IP/MAC/PORT lock switch, lock all devices in the fixed PORT of the switch, can control and prevent devices from being arbitrarily added and connected to the Internet, which can effectively prevent virus ambush The network and equipment are paralyzed, and the location of all IPs under the cooperative defense switch can be grasped from the HERHSIANG firewall.

24-port 1Gb RJ-45 + 4-port COMBO (RJ-45/SPF) 1GbE expansion interface

(Another PoE model is optional)

FOR NGS full range

Product Specification

The GS2220 series managed switches are very suitable for data center access, SMB core/aggregation, and critical PoE mission applications. There are 4 models in this series, which provide 24 or 48 network ports, PoE or non-PoE, 1GbE (GS2220 series) uplink interface and other options. The whole series supports L3 functions such as static routing, policy routing (PBR), VRRP and ECMP. It also has a hardware backup design such as internal dual power supplies, hot-swappable fans and power modules. In addition, the PoE model complies with the IEEE802.3at PoE+ power supply standard and provides up to 375 watts of power, leading the industry
