Brief Introduction
The digital coin miner is a high-end computing server and the mine farm is a kind of data center. A reliable environment with ventilation and dust resistance is required to ensure maximum hash rate, lowest failure rate and longest service life. High hash rate and returns can only be obtained in good operating environment. Therefore, never pay for your whistle just to save a small amount of money.
To maintain a good data center, you must pay attention to the temperature, humidity, dust proof and stable power. Apart from this, the miner shall be put on and taken off the shelf properly. Meanwhile, cold and heat isolation and daily inspections must be well done as well .
I. Temperature Requirement
Operation temperature: 0-40℃
However, the humidity, dust, etc. in reality will narrow the temperature range. Therefore, it is suggested to maintain the mine farm temperature between 5℃ and 35℃ with 25℃ being the optimum temperature.
Storage temperature: -20℃-70℃
Devices: hygrothermograph
II. Humidity Requirement
Relative operation humidity: 10-90%, no condensation
Relative storage humidity:5-95%, no condensation
Devices: hygrothermograph
III. Dustproof Requirement
(1) The equipment room needs to be away from industrial pollution sources, the sea or the salt lake and free of explosive, conductive (such as metal dust lamps), magnetic and corrosive (such as sulfide, chlorine and ammonia) dusts or gases.
(2) When there is sand or dust in the equipment room, you need to install a dustproof net and clean it with a vacuum cleaner regularly.
IV. Set up the Miner Properly
1. Before setting up miners, pls check whether there are violent stubbing hints, whether the cooling fin falls off by shaking them and whether there is any appearance damage to the fan.
2. Check the wiring (for the fan and hash board) and power cable are properly connected to avoid loosening
3.The miner shall be powered off before setting them up and being removed off the shelf and handled gently. It is forbidden to be placed and dropped casually and carry the hash board wiring by hand.
V. Remove the miner off the shelf properly
1. Reconfirm whether the fault can be repaired on spot before removing the miner off the shelf.
2. Check whether the IP corresponds with the miner to avoid mismatch. You can reconfirm it by lighting the red light or reporting IP by the batch management tool.
3. If there is cold and heat isolation in data center, the air outlet where the miner is located shall be blocked to avoid hot air return in the process of removing the miner off the shelf.
4. The miner removed off the shelf shall be dustproof and moisture proof and be placed stably and orderly.
VI. Keep Power Stable:
1. The voltage of the miner socket shall be stable within the normal range of 220V±10%. If the voltage is too high or too low, it may cause unstable operation and burn out the power.
2. The three-phase current deviation of the power distribution cabinet shall not exceed 15%. Otherwise, the electrician shall be notified to check whether the three-phase load is balanced. The imbalance may cause voltage rise of a certain phase.
3. Check whether factory shelf and miner are grounded regularly (It is requested that the grounding resistance be lower than 4Ω.). If they are not grounded or well grounded, pls notify the professional electrician to finish the grounding work in time. If you often feel tingling by touching the miner in the process of operation and maintenance, pls check whether the grounding work is done or done properly.
4. The cable cannot be placed in the hot air area. Pls check regularly the cable aging condition.
5. Try to avoid frequent power outage in the miner farm. Planed outage is necessary. If you need to cut the power off, pls turn off the automatic air switches on the shelf by power in ascending order and finally the master switch. Before powering on, pls make sure all the air switches connecting the miner on the shelf are turned off. The air switches shall be turned on in descending order from the master switch to avoid any possible damage caused by transient voltage surge.
VII. Good Job of Cold and Hot Isolation
Cold and hot isolation must be done in the mine farm especially in the ones with high power miners.
VII. Good Job of Cold and Hot Isolation
Precautions for cold and hot isolation:
VIII. Daily Inspections in Operation and Maintenance:
You shall check the miner and mine farm in the respect of temperature, humidity, miner appearance, the environment condition and power condition. Pls refer to the attached table for detailed inspection items.
VIII. Daily Inspections in Operation and Maintenance:
Good execution of the listed contents above at the same time and offering your high-end server a good operating environment are powerful measures to ensure your miner high hash rate and high returns!
