Next-generation PoE switches that add advanced networking and security features for outdoor applications

June 03 , 2023 0

PoE switches designed for outdoor applications in smart buildings and smart cities support services ranging from public Wi-Fi and video surveillance to connected street lights, so there is a growing need for better reliability and cybersecurity protection. Microchip Technology introduces the PDS-204GCO switch, further expanding its line of PoE switches with high industry standard outdoor protection. The PDS-204GCO switch provides enhanced network protection and the high network availability redundancy required for mission-critical applications over long distances.

Iris Shuker, Director of PoE Business Unit at Microchip, said: "Like our PDS-104GO switch, the PDS-204GCO meets the high standards of the outdoor industry and is an extremely easy and secure design to install. It also better supports applications that collect large amounts of critical data from widely distributed POE-powered edge iot devices. It addresses the dual challenges of network security and network availability from the endpoint to the central management system."

PoE technology enables the installation of edge iot terminals quickly and easily by powering a standard Ethernet infrastructure. Outdoor PoE switches connect these devices to the network and can power them under a variety of environmental conditions while monitoring status, including remote reset. Microchip's PDS-104GO switch is the first to support the industry's Ingress Protection 67 (IP67) high water resistance rating without having to open the device during installation and without compromising safety, performance or reliability. The PDS-204GCO switch also adds Ethernet network security features to protect applications from threats at all network levels and adds redundancy for high network availability.

The PDS-204GCO offers four PoE Gigabit Ethernet ports supporting the IEEE 802.3bt (Type4) standard and two small pluggable (SFP) fiber links, each supporting speeds of 1 Gbps or 2.5 Gbps per second. The fiber link can be used as an optical uplink port for surveillance cameras and as a redundant uplink to increase network availability. It supports ITU-T G.8032 Ethernet Ring Protected Switching (ERPS) technology, ensuring that communication can continue in the event of an uplink failure. The PDS-204GCO switch also supports multiple network topologies, and multiple devices can be connected in series using a Daisy chain topology to extend the coverage of the main central switch while reducing the number of cables each device connects directly to it.

The network security features of the PDS-204GCO protect the data traffic transmitted within the switch and the system management of the switch. Key functions to protect data transmitted within the switch include end-device authentication and authorization, manual switch traffic policy management, and denial of service (DoS) attack prevention. Key features that protect switch management and configuration include authentication with self-signed or Certificate Authority (CA) signatures to protect network browsing, and user authentication and authorization by remote servers using RADIUS or TACACS+ security mechanisms.
