An in-depth manual for Bitmain Antminer D7 Onshelf and Maintenance in Low-Temperature Areas is provided here.
Some cold regions can experience low temperatures of minus 10 to 20 degrees Celsius, which is different from the Bitmain Antminer D7’s preferred working temperature of 0 to 40 degrees Celsius. With the help of this manual, you can prevent and fix problems like burnt hashboards, missing hashboards, missing chips, low-temperature protection, high-temperature protection, and temperature failure brought on by low temperatures.

I. Inspections before Installation
- Jolts and collisions could occur while in transit. Shake the Bitmain Antminer D7 miner to look for any loose heat sinks. If the miner makes an unusual noise, the heat sinks could separate during transport. Don’t proceed with the installation.
- The temperature can be very low in some chilly areas. After a long journey, the miner’s internal temperature could be much lower than zero degrees Celsius. Once the equipment has been unpacked, please warm it up for 30 minutes under 25 degrees Celsius (in a hot air area, for example, in a mining farm), then set it up on shelves.
*As the miner warms up, the water vapor inside the device is spread out and the temperature of the miner is raised. As little moisture as possible should be present in the miner’s preheating area.
II. Preparation before Powering-up
When it is working and above 0 degrees Celsius, the Bitmain Antminer D7 will go into protection mode at a temperature of minus 5 degrees Celsius. If the air entering the miner is colder than minus 5 degrees Celsius, it must be warmed up before use. The method of warming up is as follows:
- Adjust the airflow
Send the heated air that was released from the miner back into the cold air zone. Change the miner’s angle and rotational direction. The incoming air temperature can be raised by adjusting the amount of incoming and outgoing air (while making sure that neither is obstructed).
*Note: To avoid extreme situations like single-point heating or air blocking, make sure the miner is heated evenly during preheating.
III. Operation After Booting
- Check the firmware to make sure it is the most recent version. If the most recent firmware isn’t already installed, you must do so before configuring the pool. Visit our Bitmain Antminer D7 firmware page to get the latest version of the firmware.
*After downloading the firmware, please double-check the MD5 value.
When upgrading a single machine via the website, kindly use one of our recommended browsers, Google or Firefox. If you use a different browser, upgrade issues might develop. If the following problem occurs during the upgrade, please restart the miner before moving forward.
The BTC tool or the Antpool batch tool should be used for batch upgrades.
- Notes on Firmware Upgrade
- Because the low temperature is more difficult to form at noon, please try to update the firmware then. You might need to change the Bitmain Antminer D7 miner’s angle and position or add more heating equipment to increase the temperature at the air inlet, depending on the specifics of the mining farm. So, don’t enable the low-temp protection mode because doing so prevents the miner from starting.
- It is better to update the firmware one shelf at a time rather than all of them at once. If everyone is upgraded, the volume of hot air would drop when the miners stopped digging, causing a group low temperature to develop. When upgrading one shelf at a time, the opposite and adjacent shelves can still be used while the upgraded shelf is in use and some hot air that was lost can spill over, which is generally preferable.
- Start at the top shelf and work your way down when upgrading a miner shelf. While the ones in the top area are being upgraded, the others in the bottom area are still in use, which also helps the upper machine’s air inlet temperature to meet the requirements.
- Having verified that your device is using the most recent firmware, you can configure your IP address and mining pool.
- If you’re unsure how to tell if the miner is running the most recent firmware, please use the BTC tool provided by our company to scan the machine status once, export the.csv file, and send it to our customer service (the file naming format is name + scan time.csv).
IV. Attentions During Operation and Maintenance
- After the firmware upgrade is completed, if the hashboards missing issue still happens frequently, you can use the function of “locate” to light up the Use the LED on the Bitmain Antminer D7 miner’s management page to find it, try to unplug it, wait at least a minute, and then plug it back in. 2. If the previously mentioned method is unsuccessful in fixing the problem, you can try shaking the miner while it is unplugged to see if any heat sinks are in danger of coming loose. If the chips or heat sinks come off, it needs to be fixed.
- Please contact customer service if there are too many anomalies, like a missing hashboard and a low hashrate.
- The machine will automatically enter protection mode if the temperature is unusually low or high. It ought to be put to use right away once the temperature has stabilized. In extremely cold or extremely hot temperatures, repeated restarts should be avoided as they could damage the equipment.
- *Notes on restarting
- In the event that the miners that have already been reinstalled are acting strangely, please avoid direct startup at low temperature and instead use the preheating startup method described above.
- After scanning reveals that the miner is abnormal because of low temperature, it is crucial to raise the temperature first. It’s not advisable to restart immediately in the background.
- If the low temperature drops to minus 5 degrees Celsius or lower, the machine will automatically activate protection. The miner’s ideal operating range is between 5 and 35 degrees Celsius.
