20 January 2022
QTECH Company presents a novelty in the line of <b><a href="https://www.qtech.ru/catalog/switches/access/qsw_3420/">QSW-3420</a></b> access switches - the <b><a href="https://www.qtech.ru/catalog/switches/access/qsw_3420/qsw_3420_28t_poe_ac/">QSW-3420-28T-POE–AC</a></b> - controlled L2+ switch with PoE support. Multifunctional and high-performance switches of this series are characterized by increased security. They are reliable in operation, easy to set up, trouble-free in the most difficult operating conditions. <br><br>
The functionality of the switching equipment meets all modern requirements, allowing users to connect to a secure IP network of both a large enterprise and a medium or small business company. <br>
<br>
Comprehensive QoS capabilities provide the highest priority for mission-critical data - streaming video and voice traffic. <br>
<br>
The switches are equipped with powerful security features: IP source guard, DHCP snooping and ARP inspection, which effectively detect and block network attacks by intruders. <br>
