to the video source display. If the output is still abnormal, check the video source and replace the good video source. If the output is normal, perform step 3. 3. Check whether the cables are in good contact. Method: Re-unplug the copper cable connecting the signal source and display. If the display is normal, it means that the connection interface is loose and has poor contact. Check the connection port to compact the connection, and be sure not

In the formation of local area network, in accordance with the general wiring of generic specifications, the construction should be used with "rice standard" network cable or on both sides of the crystal head set dedicated "special-shaped number", and in the cabinet to do with "rice mark" or "Number tube" corresponding to the computer identification record Many units have a small number of original computer

When laying the cable of the movable floor, the interior clearance of the movable floor should not be less than 150 ㎜; if the air duct used as ventilating system in the movable floor, the floor clearance is not less than 300 ㎜. (1) Groove and lattice groove must be in communication. (2) The Groove cover plate can be opened and flush with the ground, and the waterproof measures should be taken at the outlet of the cover plate and outlet. (3) The wid

(suitable for vertical and horizontal) is a cluster line of vertical combustion test, so the fire level is much higher than iec60332-1. More importantly, life-saving devices will be more likely to isolate flames, while also significantly reducing the chain of fire-induced risks. In the IEC60332-3 standard also divided into a, B and C-class. Level a requires more cables for testing, and the flame burning time is 40 minutes when tested, and the flame burning time in accordance with the C-level t

Based on the continuous development and application of new technologies, such as cloud computing and IoT, network demand for bandwidth is increasing, especially in the cloud computing environment in the data center will be a large number of virtualization technology, thereby maximizing the utilization of server equipment, which requires a higher bandwidth cabling system to support the cloud Computing data Center network communication, 10G (Gigabit Ethernet) application has become the mainstream,

With the development of the network, as a kind of medium for transmitting data in the integrated wiring system, optical fiber is more and more used by people because it has the advantages of high transmission rate and far distance. As we all know, optical fibers are non-conductive, can be free of shock current, optical fiber cable also has good protection performance, the metal components in the

First, the preface In the context of the large increase of global data traffic, data center construction tends to the direction of cloud computing, while the cloud Computing data Center will use 10G, even 40g/100g and other high-speed network applications based on fiber transmission, and the application of virtualization technology also put forward higher requirements for network transmission, Presents new opportunities for the application of optical fiber systems. While China's national standa

Notice on wiring: Features of leather Cable Leather cable is commonly known as Indoor Hanging optical cable, leather cable learning name: Access Network with butterfly introduced optical cable; because of its shape is Butterfly S

Recommended cable selection for LAN Monitoring System Integrated Wiring In the LAN, the monitoring system is widely used, including transmission lines, hubs, network management centers, and other devices. The information network is based on the Integrated Wiring System, it directly affects the performance of the security monitoring system. In this regard, it is

, with the application of a new generation of blade servers, the maximum heat load of the rack can be as high as 15 kW to 25 kW. The acceleration of Small-space and high-density computing systems puts forward higher requirements on network performance. Countermeasure: through centralized products and smart wiring, power consumption is reduced while wiring density is increased. Ampu
