Four major challenges for purchasing Internet cafe equipment (1)

Internet cafes are an industry with a relatively large investment. In addition to basic costs such as equipment purchase, installation, and decoration, equipment maintenance, use, upgrade, and other expenses must also be incurred, such as the cost of electricity, maintenance after equipment failure, and the cost of equipment replacement after equipment damage or theft, these are the biggest expenses of Internet cafes in operation. It can be said that the profits of Internet cafes are closely related to these fees. Saving electricity fees and reducing equipment maintenance costs will reduce a large amount of money in Internet cafe operation. Therefore, when buying network equipment, the Internet cafe owner must consider the energy saving, durability, security and stability of the equipment.

I. Energy Saving of equipment: directly saving electricity fees

Energy-saving is a topic that Internet cafe owners currently pay more attention to. Therefore, when purchasing Internet cafe computers, they will pay attention to the energy-saving effects of core computer accessories, power supplies, and displays, however, they ignore the energy saving of network equipment. In fact, Internet cafes operate for 365 days a year, and the overall power consumption caused by various network devices cannot be ignored. It is understood that the core switch used by Internet cafes, the actual power of common products is about ~ Between 365 and 7000, if the calculation is based on X 24 hours, the annual power consumption is approximately ~ The annual electricity cost of a core switch is 13 thousand ~ Between 20 thousand RMB, if a large Internet cafe with 300 computers must also be equipped with a router, a network firewall, and 6-7 L2 switches, the total annual power consumption is estimated to be around 50 thousand kilowatts, the cost of one year for network equipment alone has reached 50 thousand yuan.

The high power consumption of network equipment has a very high impact on the operation cost of Internet cafes. Therefore, many vendors have launched similar energy-saving products. These products have been optimized to reduce the power consumption of network devices by at least 30%. For example, they can intelligently determine which interfaces have been connected to PCs, and whether the PC is in operation, thus stopping power supply to unused interfaces. In addition, it can judge the length of the network cable connected to each port, so as to adjust the power strength of the output signal, do not waste every point of energy D-Link launched by the DGS-1024D green switch, maximum energy saving up to 50%, it can freely detect the computer's open and closed status. If the computer on the network is shut down, the router automatically switches to the standby mode, so that the average energy saving can reach 44%, only the energy saving effect of the core switch, you can save tens of thousands of yuan of electricity in one year. When purchasing network equipment, the Internet cafe owner should pay attention to whether the following products are labeled with "energy-saving Star.
