1. Not enough hash rate
2. Fewer hash boards
3. Chip lost
Causes and solutions
1. Insufficient hash rate. The hash rate is lower than the standard hash rate, which is generally caused by network instability, network packet loss, unstable mining pool connection, and high rejection rate, all of which will affect the hash rate. First of all, it is necessary to check the local area network of the mining farm to eliminate unstable factors, usually the virtual connection of the network cable or the problem of the network equipment itself. You can replace the network cable, use the network cable finder to find the faulty network cable, or ask the network administrator to assist in the troubleshooting. Secondly, network operators have network problems. Miners have requirements on the upstream and downstream of the network, and the dedicated line and downstream are equal. In addition, a 4G card is not recommended to surf the Internet. Because the signal strength is directly related to the network quality, if the signal is weak, it will directly affect the network, resulting in a low hash rate.
2. Interference or unstable power supply. The network needs to be well shielded, the sockets and combined shelves are well-grounded, and the grounding resistance is generally less than 4Ω. If the power supply is unstable, the power supply needs to be replaced.
3. The cable is abnormal. For example, the data cable is loose or broken due to transportation or vibration. If it is loose, re-tighten the data cable to restore it. If it is broken, replace the data cable.
4. The hash board is missing, or the chip is incomplete. This is damage to the hash board, and it probably needs to be repaired or replaced with a new hash board.
