The S9 status light of ant miner is not on

1. Hello
What miner are you talking about? Is it the S9 of bitcoin ant miner
if your miner is a small ant series miner, you can rece the noise by changing the fan and appropriately recing the chip frequency. But it's still very difficult to keep quiet.
if you have a large amount of electricity, you can choose a professional hosting mine company for hosting. The electricity charge will be cheaper than that of residents, and you don't need to worry about noise problems, which will cause complaints from neighbors.
if you need anything, you can send a private letter to me

if all the cables are connected, we can turn on any connected PC at this time. Turn on the network neighborhood property
2
and then turn on the local connection property
3
and then turn on the TCP / IP protocol property

4. blockchain technology is now involved in many application fields, such as finance, logistics, medical and other instries. For example, blockchain technology uses electronic bills to view all medical bills with one click; For example, the okex exchange can buy digital currency to increase wealth. Blockchain technology is still in development, I believe it can bring more surprises.

6. This is not, er, the reason for the mobile phone. The breathing light of S9, including the breathing light of S, has been compared in the past two years. Er, it's not very bright. It's obvious that he designed it like this.

7. If you have enough daylight in the daytime, you can't have dim light at night unless you have night vision function
the monitor is a monitoring software with outstanding round hole performance, and remote monitoring can be realized by inputting the IP and control password of the other party. The software uses UDP protocol to penetrate the intranet. Without port mapping, users can connect to remote computers in any computer that can access the Internet for remote office and remote management. With the increasing popularity of monitoring system in commercial and civil, surveillance cameras are widely used in various fields to protect social security. Video surveillance cameras are widely used in residential buildings, real estate villas, shopping malls, shops and financial rooms to ensure public security.

8. The status light is not on because the indicator button is turned off, so it is not on.

router signal indicator light

1. If the signal indicator light is not on

the signal indicator light is not on, it should indicate that there is no signal transmission, but it is certain that the lines are normal. Use the replacement method to change the network cable connecting the computer to another computer, or use the tester to check whether there is signal transmission. Signal transmission is the problem of local network card. Practical work experience has proved that it is a common router failure that network card leads to no information transmission

first of all, check whether the network card is installed normally and whether the IP settings are wrong. You can try to Ping the IP address of the local computer. If you can ping the general IP address, it means that there is not much problem with the network card. If not, try to re install the NIC driver

for some network cards with integrated network card or low quality, it is easy to be unstable, that is, all the settings are correct, but the network is blocked. To this end, you can disable the network card and then re enable it, which will also have an unexpected effect, They are connection status indicator light and signal transmission indicator light. In normal state, the connection status indicator light is green and always on, and the signal indicator light is red. Normally, it should keep flashing

if the connection indicator light, that is, the green light is not on, it means that the connection between the network card and the hub or switch has router fault. If the switch to the network card is interconnected by multiple moles, the dichotomy method can be used for fast positioning

generally, this kind of router failure is mostly e to the network cable is not firmly connected, the use of inferior crystal head and other reasons. The failure point is mostly the problem at both ends of the connection, such as the connector at the port of the switch and the network card connecting to the computer. With the help of the tester, it is very easy to find out the router failure and solve it

(1) when we use IE to visit a website for the first time, the firewall will ask whether the program is allowed to access the network. Some users will continue to use this setting because they are not allowed to do so carelessly. Naturally, the network is blocked. The thorough solution is to remove this restriction in the firewall

(2) in order to ensure the security of LAN, many friends have installed some firewalls, which is easy to cause some false failures, such as ping can not access each other's computer, can not access the Internet but can use QQ, etc

it is very simple to judge whether the router fault is caused by the firewall. You only need to turn off the firewall temporarily, and then check whether the router fault exists

Fourth, speed down use

many network cards use 10m / 100M adaptive network card. Although the default setting of network card is adaptive, there may be some mismatches e to the speed of switch or the making method of network cable

right click the local connection to open its property window, click the configuration button in the General tab to switch the opened network card property window to the Advanced tab, select link speed / plex mode in the property list, select 10 full mode in the value drop-down menu on the right, and then click OK to save the settings
