The red light of ant miner L3 is flashing all the time

1.

bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

extended data:

bitcoin is the first distributed virtual currency. The whole network is composed of users and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

bitcoin requires a private key to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself. Bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster execution of the transaction

As a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay. Users can explore the computing power of different hardware on many platforms

3. The red light of the optical signal of the optical fiber cat is on, which means that the optical fiber cat can not receive the signal. The common reasons are as follows:
1, unqualified fusion or fracture of optical fiber at the joint
2, the cold joint at the splitter box is not inserted well or the cold joint is broken
3, the joint at the bare box is not inserted properly
4, some part of the line is damaged and broken
in general, users are unable to repair this kind of fault by themselves and need special personnel and optical fiber tools. It is recommended to call the network operator for repair.

4. This kind of situation also has to be divided into different situations. If there is something that is forbidden, you can only wait patiently and wait for the release before you go. If the red light is broken, you can only see the safety before you pass.

5. The printer is a common office tool. When the printer runs out of ink, the indicator light will turn red. At this time, you must add ink or change the ink cartridge. Sometimes, if you still can't print normally after adding ink, you need to adjust the hardware of the printer
1. When the printer is about to run out of ink, its indicator will turn red. At the same time, a dialog box will pop up at the bottom right of the computer screen, prompting you to "add all the ink in the ink bin to the mark line..." no matter which brand of printer, the prompt is to express this meaning, which is similar. At this time, add ink quickly to prevent printer hardware from being damaged e to lack of ink
2. Click next according to the prompt in the previous step, and a new dialog box will appear, which will prompt you what brand of ink you want to use for the printer. You can't add the ink that the printer can't use at will, which may cause damage to the printer, And there are tips on how to replenish the ink
3. At the ink cartridge of the printer, open the cover above the ink cartridge and take out the ink cartridge. Pay attention not to take the ink cartridge hard. It is connected to the printer and connected through a hose. Hard pulling will cause the ink pipe to break. You will find that the ink in the ink cartridge really needs to be added, but the amount of ink that different colors may lack is different, because the demand for different colors of ink in printing is different. Don't worry about it, which is less, which color will be added
4. After adding ink, print again. Sometimes, even if the content can be printed, a dialog box will appear at the bottom right of the computer screen to prompt that there is no ink, and the indicator light of the printer will always flash red. This is not to mention that after printing several copies of content, the printer will not work at all. It is clear that it is full of ink. Why do you have such troubles? Maybe you suspect it's the quality of the ink, but it's not
5. You may also suspect that it is caused by paper shortage or paper jam, so you recheck the paper part of the printer several times, but still can't solve the problem effectively. You may suspect that the front cover is not properly covered, so you can open it and cover it several times, but it still can't solve the problem. Of course, sometimes there may be problems in other places, but the key problem is still caused by the memory of the printer, because of the lack of ink before
6. This may be because the ink cartridge is not the original one, because the ink you add may not be proced by the original factory. If you throw away the old ink cartridge and replace it with a new one, the problem may be solved, but the cost of replacing the original ink cartridge is usually very high. So, we use other methods to solve the problem, considering that the printer chip has memory
7. In fact, it's not difficult to say the method. One solution is usually to solve the problem, that is, at a button of the printer, the button is an inverted triangle. For example, the Epson printer is shaped like this, that is, press the button with your finger for 5-6 seconds on the red light, and then press it for a long time. At the same time, move your finger to the left and move the center of gravity of the handle, Print again and find that the red light here is not on.

6. If the Los light turns red or flashes, it is usually caused by the following conditions:
[1] there is a problem with the optical interface of the optical cat, and the optical cat needs to be replaced
[2] the connector of indoor pigtail optical cat is loose, and it can be restored after the connector is inserted
[3] the bending of some indoor optical fibers is too large. Over bending of optical fiber will affect the total reflection transmission of optical signal in optical fiber, as long as the optical fiber is straight
[4] if some outdoor optical fibers are broken or the optical port of the equipment in the computer room is faulty, the staff should be contacted to report the fault.

7. Hello
you can restart the optical fiber cat and other devices for a try. If this is still the case, you can call the customer service hotline and ask the staff to check and handle it for you.
