There are many things worth learning about wireless switches. Here we mainly introduce how to choose high-performance wireless switches and what problems should be paid attention to during the purchase process. In order to ensure the reliability of POE power supply, currently, all the mainstream wireless switches in the market have single-channel wireless APs and adopt the IEEE 802.3af standard. The output power has reached about 0.15 million. Solving

When enterprises integrate data centers and voice technology, they may consider meeting the environmental conditions required for the operation of new devices in advance. However, when enterprises switch from a TDM-based phone to an IP phone, meeting the needs of the wiring room environment is often ignored. When deploying an IP phone to a desktop, users will soon face the same problems as local broadband providers. These problems may cause the system to fail to run normally, or cause higher cos

There are many things worth learning about the 24-port switch. Here we will mainly introduce the detailed descriptions of the various parameters of the 24-port switch. In network equipment, the 24-port switch may be the most familiar device of network administrators, in particular, access layer switches. However, when purchasing switches, network administrators may be confused when many brands seem to have identical technical parameters. So what are the nuances of different vswitches? The follow

There are many points worth learning about the gigabit network management switch. Here we mainly introduce the basic principles of the gigabit network management switch. NETEGAR's Fast Ethernet and 1-gigabit Network Management Switch have maximum throughput and flexibility-as a high-speed, high-density Working Group access on the edge of the network, as the central backbone switching device of a growing commercial network, or applications that require high-speed connections between files with hi

When selecting a 24-port Gigabit Switch, we need to consider the number of its Mbit/s and Gbit/s ports, and then we can know the bandwidth value of its backboard. In network equipment, switches may be the most familiar equipment for network administrators, especially access layer switches. However, when purchasing switches, many brands seem to have identical technical parameters, network administrators may be confused. So what are the nuances of different vswitches? The following describes the m

The most widely used switch for small and medium-sized enterprises is the 24-port Gigabit Switch. Therefore, when purchasing a switch, you must make full consideration. A clear purpose is to save costs for everyone. In network equipment, switches may be the most familiar devices of network administrators, especially access layer switches. However, when purchasing vswitches, network administrators may be confused about the technical parameters that many brands seem to have identical. So what are

Some minor differences can determine the performance of a vswitch, which is the same for access layer switches. Therefore, when selecting a vswitch, we need to carefully understand its parameter indicators. In network equipment, switches may be the most familiar equipment for network administrators, especially access layer switches. However, when purchasing switches, many brands seem to have identical technical parameters, network administrators may be confused. So what are the nuances of differ

the main stream and the code flow two parts, switch interface rate selection of the most important is to consider whether the upper port can host all the camera's total code flow. For example, 20-way 2 million-pixel camera, the main stream is 20*4m=80m, the code stream 20*0.5m=10m, the total bandwidth of 90M. Considering the burst traffic and other data terminal bandwidth, it is recommended to select the Gigabit Allied switch. 2 , PoE

Commercial Building Market in 2018: evolution from intelligence to intelligence, building in 2018 Chen LAN, vice president of Enterprise Network North Asia For the commercial building market in 2018, the four trends defining the development of network technology will promote the transformation from intelligence to intelligence: mobility, network security, low-voltage power supply, and office efficiency. These trends will also affect the types of network infrastructure and equipment deployed in

. USB interfaces are used to detect devices before they are connected. Therefore, USB ports are more and more common in vswitches because they have a higher security factor than the CF card. USB ports can be used to connect USB flash drives, mobile hard drives, and CF cards (using USB interface standards) to other storage devices. This allows you to expand the storage space of switches. POE A switch can not only forward data, but also Power other devi

Most network administrators are willing to manage networks only, but changing situations always force them to expand their responsibilities. Just as the current management of energy consumption and conservation technologies. You may think that network-based IT Power Management has appeared in the previous generation of Ethernet power supply (PoE), which turns the data network into a primary power network. In various generations of
