How to select a 60W PoE switch for security projects To ensure the high performance of a 60W switch, the selection of high-quality key parts and components is crucial. PoE products operating in transportation, critical infrastructure, factories, and other industrial environments should be toughened up to stay functional and durable amid extreme weather, vibration, and electromagnetic interference (EMI). In harsh environments, video surveillance cameras are usually equipped with an extra heater and sometimes even IR functions, and the resulting high power consumption creates another challenge for the PoE switch. Therefore, quality assurance should begin at the product’s initial design stage, with parts and components carefully selected and vetted. The printed circuit board must be carefully designed to ensure it works well with the key parts and components. Besides meeting general requirements, the circuit board must be able to function in extreme temperatures – with circuitry meeting the comprehensive requirements of EMC standards. In addition to the initial industrial design, extensive product testing is required in order to evaluate the quality of a PoE switch. For Etherwan, this includes multiple PDs (powered devices) being tested to guarantee flawless transmission between the devices and the 60W switch. Tests are even run in special chambers with the temperature set at 85 degrees Celsius, to verify functionality in extreme heat. As an example, the EX78900 switch from Etherwan provides up to 60W from each of the four ports. During testing, each port is connected to a PD. The switch passes the test only if it is functioning normally at full capacity (60 x 4 = 240W) over a temperature range between -40 degrees Celsius and 85 degrees. Compliance with general industrial standards is not enough – customers need to have full confidence that a supplier’s products and accessories are tested and approved to reach or even surpass the mean time between failure (MTBF) threshold, guaranteeing reliability while running in the most rugged conditions. Suggestions for finding a value-added partner From time to time, there are complaints in the industry about sub- standard quality found in industrial networking solutions. Some suppliers use commercial-grade parts and components for industrial devices, and then skip the extensive testing that is required. To avoid these quality issues, customers should request that suppliers provide professional test reports along with their marketing materials. Additionally, stadiums, large buildings, and other large projects, require careful selection of equipment, including components and accessories. Resistance to fire and electromagnetic interference needs to be taken into account. what’s driving the future Poe market The rise of the Internet of Things means that the launch of 60W switches has arrived amid PoE’s growing importance as a method for delivering power, not only to security devices, but also to a huge range of other devices as well. More and more, streetlights, interior lights, and building automa- tion systems are all connected to the internet for improved control and efficiency. At the centre of this is PoE technology, which not only serves as an exchange point for data, but also plays a key role in delivering power. As the advantages of PoE in delivering power to edge devices become more widely recognised, adoption will continue to increase for the foreseeable future. Future applications may include: ■ Intelligent lighting system: for applications at stadiums, streets and intersections, as well as where the lighting devices require higher watts power supply. ■ Surveillance system (with PTZ and remote-controlling): To drive the pan, tilt and zoom movements on the PTZ cameras requires power higher than 30W. ■ Outdoor digital signage: Embedded Systems (As hardened 60W PoE switch can satisfy higher power requirements). Etherwan Systems Inc. is a leading manufacturer of hardened Ethernet, PoE, and fibre connectivity products specifically designed for harsh and demanding environments. Founded in 1996 in Irvine, California, now with Pacific Rim headquarters and manufacturing in Taipei, Taiwan, Etherwan specialises in the design and manufacture of Ethernet switches, media converters, Ethernet extenders and power over Ethernet products for applications where connectivity is crucial.
