How to connect the A3 power line of ant miner

1. Ant miner S9 is a bitcoin miner. The algorithm of bitcoin is SHA-256, so as long as it is a digital currency based on bitcoin algorithm, ant miner can dig. However, the S9 of ant miner with other algorithms, such as ether coin or Wright coin, can't dig
ant mining machine S9 is a mature and widely used coin digging machine at present. Its advantages lie in its good quality, simple and stable coin digging, easy to use, and can be used as long as the power line is connected.

2. If the power supply is broken, replace it directly. It must be because the power supply is broken, the output current is unstable or the output current is unstable. The function of the power supply is to convert alternating current into direct current. Half of it is not repaired, and it is not expensive. Just buy a new one

3. Grounding wire is for safety, not grounding will not affect the normal use

4. Although it is copied, it is still useful<

there are hundreds of commonly used subnet masks

here we only introce the two most commonly used subnet masks, which are "255.255.255.0" and "255.255.0.0"

1. Network with subnet mask of "255.255.255.0": the last number can vary from 0 to 255, so 256 IP addresses can be provided. However, the number of available IP addresses is 256-2, that is 254, because the host number cannot be all "0" or all "1"

2. Network with subnet mask of "255.255.0.0": the last two numbers can be changed arbitrarily from 0 to 255, and 2552 IP addresses can be provided. However, the number of available IP addresses is 2552-2, that is 65023

the subnet mask setting of IP address is not arbitrary. If the subnet mask is set too large, that is to say, the scope of the subnet is expanded. According to the subnet routing rules, the data sent to the destination machine that is not in the same subnet as the local machine will be considered to be in the same subnet because of the wrong judgment. Then, the data packet will cycle in the local subnet until it times out and is discarded, so that the data cannot reach the destination machine correctly, Causes the network transmission error; If the subnet mask is set too small, the communication between machines that belong to the same subnet will be regarded as cross subnet transmission, and the data packets will be handed over to the default gateway for processing, which will increase the burden of the default gateway and rece the network efficiency. Therefore, the subnet mask should be set according to the size of the network

if the scale of a network does not exceed 254 computers, it is OK to use "255.255.255.0" as the subnet mask. Now most LANs will not exceed this number, so "255.255.255.0" is the most commonly used IP address subnet mask; The largest primary and secondary school campus network that the author has seen has more than 1500 computers, and the LAN of this scale can use "255.255.0.0"

default subnet mask

in Windows 2000 server, if an IP address is specified for a network card, the system will automatically fill in a default subnet mask. This is a subnet mask automatically generated by Windows 2000 server to save user input time. For example, the IP address "192.168. X.x", which is most commonly used in LAN, has a default subnet mask of "255.255.255.0". In general, the IP address can use the default subnet mask.

6. There are more than 2400 operating platforms in P2P online lending instry, of which there are nearly 90 in China, accounting for 3.56%. Generally speaking, there are too many companies and we still have to choose. Therefore, if we don't know who to consult, we can go to a professional platform to learn. For example, today's talents are quite good.

9. The GEM stocks with the background of state-owned assets are as follows:
Lepu medical

AVIC test
gem, also known as the second board market, is a securities exchange market outside the main board that provides financing channels and growth space for small and medium-sized enterprises and emerging companies that can not be listed temporarily, It is an effective supply to the main board market and occupies an important position in the capital market. Most of the companies listed on GEM are engaged in high-tech business, with high growth, short establishment time, small scale, and low performance. Gem officially opened on October 23, 2009. Gem is a new market set up to meet the needs of entrepreneurship and innovation. Different from the main board market, which only accepts mature enterprises with sufficient scale to be listed, gem takes growth start-ups as its service object, and focuses on supporting enterprises with independent innovation ability to be listed. It has the characteristics of relatively low threshold for listing and strict supervision of information disclosure, and its market risk is higher than that of the main board.

10. Almost all the power generation companies are state-owned
the first echelon: Datang Power, Huaneng International, China Power (Hong Kong stock)
the second echelon: Hubei energy, China Construction Investment energy, Wanneng power, Zhangze Power, Ganneng shares
