Dear partners & colleagues: The Spring Festival of 2022 is approaching. In consideration of the actual situation of our company, we hereby make the following arrangements for the Spring Festival holiday in 2022: The Spring Festival holiday will be from January 29, 2022 (the 27th day of the twelfth lunar month) to February 7, 2022 (the seventh day of the first lunar month), a total of 10 days. Work will officially resume on February 8, 2022 (the eighth day of the first lunar month). Hereby, we would like to express our gratitude to our partners, colleagues, and family members for their continuous support and trust in Huanghao

TOR Switch: An intranet access switch, a 1U box-type network device, equipped with 48 10G optical ports and 4 40G optical ports; the 10G optical ports are connected to the 10-gigabit ports of servers using AOC cables, while the 40G optical ports are uplinked to the intranet core of the server room using MPO fiber. A single TOR covers server access for 2 cabinets;
ILO: Server ILO access switch, also known as management network access switch, is a 1U box-type network device equipped with 48 10/100/1000M adaptive electrical ports and 1 1/10G optical port. The 48 electrical ports are connected to server gigabit network ports and network device MGMT ports; the optical port is connected to the core of the machine room management network using 10G multimode fiber. A single ILO covers the access of servers and network devices in 2 cabinets;

With the deepening development of smart cities, more intelligent hardware facilities are gradually being deployed in urban construction, and the construction of smart light poles is one of them. As an intelligent information dissemination device, the combination of smart light poles and LED light pole screens has achieved great results once deployed, and has become a beautiful urban cultural landscape. It has made great contributions to the dissemination of urban information and cultural development, the promotion of civilized city construction, the enhancement of urban cultural image and taste, the creation and construction of digital city construction level, and the service and convenience for citizens.

1、 A few misunderstandings about VGA, DVI, and HDMI: Misconception 1: HDMI is high-definition, VGA is not. These three are not equivalent. HDMI and VGA are both signal transmission methods, while HD refers to a video resolution. HDMI supports high definition, and VGA also supports it. HDMI currently supports high-definition formats up to 3840 * 2160 resolution and 50FPS, 60fps frame rate. VGA supports various resolutions from 640 * 480 to up to 2560 * 1600, but VGA is highly susceptible to interference from other signals, so high-definition resolution may appear a bit blurry. To avoid image interference, VGA interface can be used below 1920 * 1080P resolution.

 Calculation of equipment materials and cables: L=1.1 × (LMAX (maximum)+LMIN (minimum))/2+6, where L is the average amount of wire used per information point. LMAX: represents the distance between the farthest information socket and the floor management room, LMIN: represents the distance between the nearest information socket and the floor management room, and is the end-to-end tolerance (mainly considering factors such as cable loss during construction and cable layout length errors), with 10% as spare margin.
The number of information points that can be arranged in a box of network cables is n=305/L (n takes an integer, omitting the digits after the decimal point)
The number of cable boxes used in this project: cable box number=total number of data points divided by n * 1.1 (considering the loss of wire laying and leaving a certain margin)
Of course, the total length of cables can also be used to calculate the required number of cable boxes.
The total number of cable boxes required is equal to the total length of each layer of cables divided by 305 meters multiplied by 1.1 (1.1 considers leaving a certain margin)
Note:
Total points=Data+Voice
Another thing to note is that the number of network cables is generally around 300 meters, less than 305 meters. If the number of cables in this project is relatively large, this should also be considered. For example, the reserved cable length at the threading equipment end should also be considered comprehensively, which will be judged based on the overall construction process of your construction team.
2. Module calculation: the number of information points;
3. Number of double port panels: total points/2;
4. Calculation of 48 port distribution frame:
