9 Problems You’ve Had Sourcing PoE Switches in China

Sourcing PoE Switches in China

Content Directory

In 2010, Chinese communication companies entered the PoE field with the divergent thinking and night and day efforts and attempts of Chinese IT elites. PoE switches have gradually replaced the PoE power supply in the leading position of PoE products. PoE switch products are widely used in the field of video surveillance. Through active research from 2010 to 2013, Chinese companies, represented by the pioneers of PoE China, gathered in Shenzhen, China. From the introduction of PoE technology to the localized innovation of PoE technology, from the simple assembly of production to the in-depth manufacturing of PoE products. PoE products’ technical and manufacturing advantages in Shenzhen, China, gradually emerged in 2014. It has quickly replaced the PoE leadership position occupied by Taipei, Taiwan in the pre-PoE era and become the new global leader in PoE switch products. We provide high technology, high quality, and fully priced PoE switch products worldwide. Shenzhen, China, has become a mecca for global communication brands looking for ODM and OEM procurement of PoE products since 2014. The rapid rise of PoE switches in China has accompanied many unscrupulous business people speculating and fishing in troubled waters. To this day – 2020, we still see overseas PoE switch users in China to purchase PoE switches are still encountering all kinds of problems. Not only to overseas communication brands buying manufacturers suffered losses. At the same time, it wastes time, misses business opportunities, and damages the interests of direct users. For this reason, the problems encountered by overseas customers purchasing PoE switches in China over the past ten years are summarized below. Let the excellent PoE switch vendors provide quality PoE switch products and services for overseas purchasing users.

non-standard PoE switches

The development of PoE technology benefits from the IEEE802.3af, IEEE802.3at, and IEEE802.3bt standards introduced by the International Electronics Industry Association, which are 15.4W, 30W, and 60~90W in port power supply, respectively. To provide PoE switch products more quickly, many unscrupulous domestic merchants first bypass product development and reduce the hardware cost of PoE switch. They omit the PSE chip and directly load and couple 48V DC to the network cable. They attract customers to buy non-standard PoE switch products in bulk at a low price, causing considerable damage to overseas customers.

MCU version of PoE switch

After the first problem, quality Chinese PoE switch manufacturers have widely promoted and educated users on easy methods of testing standard PoE switches and non-standard PoE switches. The network cable shorting method or voltmeter network port voltage test method is directly used. If the shorted network port is not burned is standard PoE, and burned is non-standard PoE. If the network port can measure a voltage of 5VDC or less is standard PoE. A test voltage of about 48VDC is a non-standard PoE. Simple test methods allow overseas users to find non-standard PoE switches quickly. It will enable buyers to find better the standard PoE switches they want. However, another “alternative” PoE switch product was quietly introduced in China, driven by interest. This “alternative” PoE switch is now known as the industry’s monolithic PoE switch. The product imitates the professional PSE chip’s detection model for PD devices by adding a single chip. When there is no access to PD devices, the same can not power. Of course, this imitation is not always effective and can fail intermittently. Of course, it is even less likely to have intelligent classification, power supply detection, green energy saving, and brand compatibility. Therefore, after the customer’s bulk purchase, the product application environment is limited, and the product standard PoE performance is missing, which brings the customer a considerable loss.

Outsourcing of ODM services layer by layer

Overseas customers will purchase standardized PoE switches from China except for the channel market. Most of them need customized ODM services, To meet the unique application requirements of different areas for PoE switches. For example, appearance, wide temperature, port combination, bandwidth, special features, etc. When overseas customers choose China PoE switch suppliers, they often need to consider whether the manufacturer can provide ODM service and the technical strength to provide the customized PoE switch service. When an overseas customer knows a Chinese PoE supplier through an exhibition, Alibaba, or Google search engine, any Chinese PoE supplier will claim to have a strong ODM service capability and a senior R&D team. Yet, what is reality? According to our understanding, there are hundreds of PoE suppliers in China. However, the manufacturers with real R&D teams and R&D capability have been below double-digit. That is, 90% of the domestic suppliers of PoE switches do not have ODM service capability, so how do those PoE suppliers without R&D capability complete ODM service for overseas customers? So in the domestic PoE sector, there is the business of ODM service outsourcing, companies without R & D capabilities to receive ODM orders, and then look for R & D team PoE companies to do. From the demand to the final with R & D capabilities of PoE manufacturers in the middle of how much “PoE company” can not be determined, the price layer by layer. So the end-user cannot get the ODM quotes with sky-high prices, and multi-layered relay communication is blocked, the delivery period has also become distant. Professional PoE research and development team, reliable ODM service, better price, faster delivery, and no intermediary to earn the price difference.

high-end samples, low-end supplies

PoE switches internal chip is divided into a communication chip and a PoE chip, the two chips are the main cost of a PoE switch. Commonly used communication chips include Broadcom, VITESSE, Marvell, IC PLUS, and Realtek; commonly used control PSE chips for PoE include Microsemi, Texas Instruments, Linear Tech, IC PLUS Corp, National Semiconductor, Maxim, Realtek, etc. Each chip’s positioning is different; the application scenario is not the same. Of course, the price of the chip is very different, but for ordinary users using the standard test, methods are complicated to know what chip is used in the PoE switch. When measuring samples, we can dismantle the switch to check the chip logo and model. You can also verify the performance and functions of the PoE switch through professional testing programs. However, the customer can’t verify the information of the product chip when inspecting the goods as when testing the sample. So there is a sample of the supply of high-end chip products quoted at a meager price to attract customers to buy payment. By the time of the actual store, the low-end chip products are mixed into the batch products.

Industrial PoE switches are not industrial

We have been rooted in industrial PoE switches for several years. We have always believed that industrial switches should adopt industrial standards in R&D, materials, and manufacturing to make high-quality and high-stability industrial communication PoE products. Overseas customers choose industrial PoE switches because they want to get communication switch products that are higher than the commercial standard to provide more stable and reliable communication services. Along with the rapid development of globalization of industrial IoT, the procurement of industrial switches and industrial PoE switches steadily increased worldwide in 2018. Some in the absence of industrial communication technology support, only in the product appearance of the choice of rail-type housing, or provide dual power supply with the cooperation. Then claim to be able to produce and manufacture industrial PoE switches and industrial switch products. With the low price to attract overseas customers to purchase, the overseas customers do not know much about the industrial communication field, mislead customers, so that after the purchase customers suffer a lot of losses. Industrial switches and industrial PoE switches can continuously reduce product costs through technology development and optimization of manufacturing. Meet the wide range of industrial communication products demanded by the industrial Internet of Things.

Lack of documentation, missing or irregular certification

Suppose there is no strong support for product certification. In that case, overseas customers will often encounter an awkward situation of no certificate, fake certificate, non-compliant certificate, or failure to accept the user’s project. However, few professional suppliers can provide professional product certification and qualification services among hundreds of PoE switch suppliers in China, making overseas customers face substantial potential risks. With our professional overseas certification team, we can provide all kinds of certification services so that your purchase can go through customs and acceptance without worry.

Falsely marked parameters, pull-up function

The PoE switch has two main parameters: the backplane bandwidth which is the core parameter for communication, and the total power of the configured power supply powered by PoE. The higher the backplane bandwidth, the higher the price of the switch, and the higher the configured power supply. The problem is found in small and medium PoE merchants and large PoE leading enterprises. This kind of falsification seriously undermines the interests of overseas customers who buy low-performing products at high prices. Overseas buyers must be bright sassafras eyes, to avoid unnecessary losses.

Amplifying micro-innovation, exaggerating small features

With the rapid development of PoE technology in China, the key lies in the innovative application, functions, and innovation that has given the PoE switch to the PoE switch and plugged the wings for the broader application of PoE switch in the world worthy of recognition and appreciation. HoweVision Technologies is one of the many outstanding vendors passionate about PoE’s innovative technologies and applications. But not all innovations are worth the high price to pay, nor are they all capable of making product leaps and bounds in terms of performance and functionality. The current micro-innovations in domestic PoE switches, such as visual PoE, watchdog, priority power, red-port PoE, long-distance power, physical isolation, video streaming priority, etc., do these micro-innovations require buyers to pay high costs? What are the additional costs of developing and implementing these micro-innovations? How much real-world value can these micro-innovations bring to the user in terms of functionality? Of course, micro-innovation is promoted to reap huge profits and eyeballs, but the PoE industry is doing the damage. These are all behaviors that our overseas buyers should be aware of and avoid.

Simplify the manufacturing process, product aging is missing

The cost of the PoE switch is in R&D and materials, but also a key price is the manufacturing link. HoweVision Technology adheres to the quality first concept in manufacturing PoE switches, incoming material inspection, post-placement test, post-aging test, post-assembly test, pre-shipment test, five-time professional inspection, and testing. PCBA aging, post-assembly aging two complete inspection aging to ensure the quality of shipped PoE switch products. Of course, the complex production process will lead to an increase in product costs. But guarantee the quality of the product so that the shipping yield is 100%, and the return rate is less than 0.5%. High quality to provide overseas export PoE switch products is the common pursuit of quality PoE manufacturers. But there are also lower costs, to offer more inferior price PoE switch products, almost omitting all the intermediate processes of testing and aging. The problem is left to customers, and the defective products are mixed in the goods out to users, which significantly damages Made in China and damages customers’ interests.
