Turn on the miner to electricity and internet

Download a program to any PC / Laptop / Phone – the program will find all IPs connected to your modem (*this PC / Laptop / Phone must be connected to the same network (Wi-Fi / LAN) as the miner)

Download Program for IP Address (Windows)

Download Program for IP Address (Mac)

* (or use any other program for scanning IP addresses)

Install and run the program

The program will load IP addresses of all devices connected to your modem (phone, PC, printers ..)

One of these IPs is your miner’s IP (find out by trying)

Insert individual IP addresses into the internet browser (Chrome / Opera / Safari .. ), and at the address where a box pops up from above asking for name and password = that’s the miner’s IP address.

In case of Bitmain / Whatsminer / Iceriver miners, you can also use the IP Search Program directly from the Manufacturer

Special program for Bitmain miners Download HERE (IP Reporter)

Special program for Whatsminers Download HERE (Whatsminer Tool)

Special program for Iceriver machines Download HERE

The procedure is the same for all 3 programs / miners:

Install the program, run it and click Analyze / Start

Then on the miner (only on Bitmain / Whatsminer miners) find the small black button on the front called IP REPORTER – press and hold this button for about 5-10 seconds.

In the downloaded program, the IP address of the miner where you pressed the button should appear automatically (advantage especially if you have dozens to hundreds of miners in the data center)

internet speed (at least 7mbps download)

internet ping (max 50 ms)

Search IP using both methods above (Advanced IP Scanner, if it doesn’t work, choose the manufacturer’s program directly)

in case the miner has a static IP address set, Advanced IP scanner may not find your IP (use manufacturer’s program for IP search)

Connect the machine directly to the modem (LAN cable from modem directly to machine)

If not working, connect the machine indirectly (put a switch between modem and machine – device that mechanically “splits” 1 LAN cable to X cables)

If not working, connect the machine indirectly (put another modem / router between modem and machine – i.e. a device that also has its own internal settings and SW environment and which you power separately to electricity),

Contact your internet provider (we had a situation where the provider directly blocked mining miners)

Check the protocol for assigning IP addresses – each device “connected to the internet” has a specific IP address. This IP address is usually assigned to each device by your modem automatically (DHCP protocol = dynamic IP addresses). In some cases, however, some device (miner) has a static IP address set – always the same IP address, regardless of whether you plug the miner at home or somewhere else). For our needs, choose dynamic IP address assignment (DHCP) in modem settings.

Check firewall settings in PC (often block crypto-sites, apps .. )

Check antivirus settings in PC, or antivirus in browser

*or try to connect the miner in a completely different place (other house, office, space, where there is a different internet provider or at least different modem .. )

Operating system (Mac / Windows..) may sometimes block finding IP addresses of miners due to protection – search IP address through different devices, PC, laptops, phones .. (any application program for scanning IP addresses)

you mine e.g. LTC, you get LTC (to your external LTC wallet/exchange, which you need to create)

4a) Connection via Standard Pool (+external wallet)

Coin:	BTC	Kaspa	LTC	Kadena	Nervos	Zcash	ETC	SIA,HNS	ARRR	ALPH	ALEO
Choose Coin

or:

you mine e.g. LTC, but you get BTC directly

Nicehash is also a wallet – the yield (BTC) you can leave directly on Nicehash account (but you can also have it forwarded to another BTC wallet/exchange).

+Nicehash is also an exchange – coins here you can trade for other coins, or sell for EUR and send to bank account.

Difference Nicehash vs Standard Pool

1, Standard Pool – direct mining – you mine e.g. Zcash, as “payment” you get Zcash

2, Nicehash:

2a) Nicehash switches your miner to mining the currently most profitable cryptocurrency that can be mined with your machine (therefore NH always has slightly higher profits than other standard pools)

2b) Yields come to you directly in BTC (you don’t need 20 different wallets for 20 different coins) – without any fee (you mine LTC, you get BTC directly)

Nicehash is a platform / software:

does not work as a regular mining pool

Nicehash rents your machine’s power to other people (around the world), who don’t have enough money for a whole miner, so they want to rent only part of the power / for a certain time)

These people pay for power rental in BTC

Therefore you, even if mining e.g. Zcash on Nicehash, your “payment” always comes in BTC (in equivalent amount)

2c) Nicehash also includes wallet/exchange for various coins, so yields (BTC) you can hold or sell for EUR directly on Nicehash account and don’t need to create separate wallets/exchanges.

That’s all

You can disconnect PC / Phone, Miner will ramp up to full power in a few minutes and start mining

(Exception: for Whatsminers loading takes about 20-30 min.)

*Hydro miners (original Hydro from manufacturer) = 3 phase (about 5kWh)

*Hydro (converted from AIR-cooling machine) = mostly 1 phase (about 3kWh)

*Type of power cable (ends) for Hydro 3-phase machines (original Hydro from manufacturer): LP-20-4P

*Water temperature in the system must be at least 20°C (due to condensation)

If the temperature is lower, the automatic protection in the miner won’t even turn on the machine (to protect the machine)

Regular tap water – contains minerals, organic particles, microplastics ..

Distilled water – regular water is heated to boiling point. These vapors condense upon cooling and thus create almost pure water (almost without minerals, organic substances..).

Demineralized water – even cleaner, as minerals are completely removed from the water (calcium, magnesium, chlorides, sulfates, etc..).

Deionized water – ions are also removed – so even higher purity than demineralized water.

For mining miners, use at least distilled water.

+It is possible to add a cooling mixture (increases cooling effect).

If the water in the miner’s system is dirty after some time (physically visible discoloration), this indicates it contains minerals or impurities. The water needs to be replaced and use distilled water (see previous section).

*Water flow in the water pump = the water pump pushes water out from its bottom part sideways (to the side of the water pump). The water then flows into the miner (where it heats up), from the miner it comes to the cooler (radiator) with fans (where it cools down) and then flows back (already cooled) to the upper part of the pump, falls down to the bottom part of the pump from where it is pushed out again (to the side) and so on in a loop.

Systematics of power supply:

A) If the power supply (PSU) IS NOT water-cooled (standard for miners converted from AIR-cooling to Hydro)

Inlet (cooled) liquid is to the upper part of the hashboards

Outlet (hot) liquid is from the lower part of the hashboards

Hydro miner – connection

B) If the power supply IS water-cooled (standard for original Hydro miners)

Inlet (cooled) liquid is where the power supply (PSU) is

Outlet (hot) liquid is from the miner

Hydro miner – connection

*It is possible to connect multiple miners to 1 cooler (e.g., 12kWh cooler connected to 2 miners at once) but:

12 kWh cooler = this cooler can cool miners with 12 kWh consumption but:

We recommend leaving 20-30% reserve – so connect max e.g. 10kW miners to a 12kW cooler)

1/3 and 2/3 miner – adding Hashboard (increasing power)

#6 Firmware Update via IP Interface

1. Download the current firmware to PC through which you manage the miner (Warning – download firmware exactly for the model of miner you own. Uploading another FW can damage your miner)

Bitmain firmware HERE (official from manufacturer)

Bitmain firmware from Unofficial Producer HERE (AwesomeMiner). Increases miner power by 5-30%, but can damage the miner / reduce its lifespan)

Bitmain firmware BrainOS HERE. Czech company behind the world’s first HW Crypto-Wallet – Trezor and the world’s first mining Pool – Slushpool). Unofficial but reliable firmware that increases power by 5-15% for selected models.

Innosilicon firmware HERE (official from manufacturer)

Avalon (Canaan) firmware HERE (official from manufacturer)

Ibelink firmware HERE (official from manufacturer)

Goldshell firmware HERE (official from manufacturer) – after clicking on the web, click on Github Download (firmware download from github page)

2. Log in to the miner’s IP interface (via IP address in browser)
3. Go to Firmware section
4. Upload the file (firmware) you downloaded in the first step

6b) Firmware Update via SD Card

Requirements: PC/laptop with Windows XP or newer

SD card with capacity max 16 GB

Abbreviations in text: FW = firmware

Important: During firmware upload (when SD card is inserted in miner), you cannot turn off or reset the miner … in the opposite case, it will lead to irreversible damage to the control board.

Procedure:

SD card (max 16 GB) must be formatted to [FAT32]: In your PC (This Computer section) right-click on SD card icon -> Format -> FAT32 (default type). Confirm and in a few seconds the card will be formatted (Warning: formatting will delete all files on the SD card)

Download the appropriate firmware to PC (Warning – manufacturer usually has 2 types of the same firmware – one for update via IP interface and the second for update via SD card)

Unzip / extract this downloaded firmware (file) in PC

After unzipping, a folder will create multiple files – move all these extracted (unzipped) files to the SD card.

Insert SD card into the miner (which must be off at that time) – if you insert SD card into a running miner, the new firmware will not upload to the miner

Turn on the miner and wait (about 30 seconds, the new FW should load automatically – During upload, the red and green LED should light or flash simultaneously; After successful new FW upload, only the green LED should light).

After FW upload, turn off the miner, remove SD card and turn on the miner again and that’s it (the miner should have the new firmware – but the miner’s IP address may have changed, so search for it again)

If something doesn’t work:

remove SD card, turn off miner, then turn on miner again and after a few seconds of running, reset the miner (without SD card) using the RESET button on the front of the control board; Then continue with the procedure above (turn off miner, insert SD card with new FW and turn on miner..)

use another SD card / or different SD card model / or different manufacturer (but always max. 16 GB

for older miner try to clean the SD card slot (from dust and other impurities)

off miner–insert sd–wait 30sec until only green LED lights–turn off miner–remove sd–turn on miner

Basic First Aid

(basic steps for any problems with mining / miner):

1. Restart the machine
   • pull out of the outlet
   • or better via Reboot button in IP address interface
2. Update firmware (FW) via IP
   1. Update via IP address
   2. If it doesn’t work, update FW via SD card
   3. (update procedures see above on this page)
3. Reset – (to factory settings – changes IP, kicks out of pool, gives original FW,…)
   • via IP interface – performance reset button
   • via RESET button on the front of the machine
   • borderline reset method (doesn’t work on all models – only on machines that have SD card SLOT to the left of the Internet connector (left, not right), but not on all models). How? turn off the machine – press IP REPORTER button (yes IP reporter), hold it and during that turn on the machine (and hold the button for about 5-7 seconds from turning on the miner)
4. Cables
   • Push or disconnect and reconnect all cables (internet, electricity)
   • Same with cables inside the miner (cables from motherboard to hashboards)
   • Check if they are not visibly broken / burned
5. Change location
   • Try connecting the miner experimentally in a completely different place where #1 different power source and mainly #2 different internet provider / modem …
6. Power Supply:
   • measure power supply voltage (V)
   • Or check machine consumption when on (consumption meter). This way you monitor if the miner accidentally has too high consumption, which would indicate a problem with power supply / miner
   • check power supply cable if it is not very overheated (if yes, need thicker)
   • replace power supply with another (power supply may work and hum but no longer has sufficient power so doesn’t connect miner to pool, or miner mines at lower power)

*When did the machine last crash? Was there a storm? Did you change internet provider? Internet settings or modem?

*Try measuring consumption – if it increases before it crashes (short-term miner consumption can spike – if you have only 10A breaker, the breaker trips

* upload security FW (protected ssl – find on manufacturer’s pages)

Internet / If you can’t get into Miner’s IP Address

• If You Can’t Find Miner’s IP Address or you are in the miner’s interface, but internet causes another problem – Procedures for removing all possible errors caused by internet / modem / provider SEE HERE

Miner running, I’m in IP interface, but won’t connect me to pool

• Check if you have the correct URL pool link entered (stratum port)
• Check if you have the worker entered correctly (for some pools you enter your crypto-wallet directly into the worker, for some your pool username etc..
• For both URL link and Worker, it is true that one wrong character, or empty space before/after is enough and it won’t connect you to the pool
• If entering wallet number into worker – try another wallet (or check if you entered the address of the correct cryptocurrency wallet)
• If connection takes long, Let the miner run for 20-30 min (sometimes it takes longer to connect)
• Try another pool
• Try nicehash (nicehash but doesn’t work on all miners)
• Check Internet

Miner power is only very low (only 2-5-10-20% of the power it should have)

• this sometimes happens when connecting miner to nicehash.com (NH). Nicehash does not support all miners. You can connect the miner to NH, but it will load only minimal power in the machine. So connect the miner to another pool.
• If you have low power when connected to another pool than nicehash, change the pool to another.

1 of 3 hashboards mines only half power / or 1 whole hashboard doesn’t show at all:

• try all previous procedures (mainly reset / restart and FW update)
• remove cover and disconnect white cable (18 pin) from motherboard (the cable connected to the bad hashboard)
• If it’s ok then try connecting this faulty hashboard to the fourth free slot on the motherboard
• If it doesn’t start again / crashes, then:
  • faulty connector on motherboard
  • faulty cable connecting motherboard and hashboard
  • fault on hashboard
• check cables on motherboard (white 18-pin cables) – if not physically broken, burned
• try disconnecting this cable and inserting back (push properly) – on motherboard side and hashboard side
• Try putting the cable in another place (insert cable into fourth free slot on motherboard)
• Try connecting this hashboard with a completely different 18 pin cable that you know works (i.e. cable from another hashboard of this miner)
• or the power supply is faulty (doesn’t go to full power, so can’t pull all hashboards)
• Try tightening all screws on the miner’s frame (on top of the miner under the top cover, where the metal frame from power supply to 3 hashboards is connected) – tighten screws
• or some component is shorted (motherboard or one of the hashboards – disconnect all hashboards from motherboard and turn on miner only with motherboard (then connect one board at a time – this way you find which component is shorted)
• or one of the chips is blown, so all further chips behind this faulty one don’t load

If the miner mines, but after 5-10-20-30 min. 1 hashboard turns off or the whole miner:

• Monitor temperatures on all hashboards, probably 1 board overheats so the whole machine automatically turns off
• Or fault in power supply (when miner heats up = higher fan speeds = higher consumption and power supply doesn’t suffice)

If won’t update FW (miner turns off or still shows the original FW so doesn’t update to the new one)

1. Update FW via SD card
2. Try updating firmware via SD card 3-4-5-6 times (we had cases where FW took on the 5th try) + combine with machine reset
3. Flash SD Card Image – to recover Control Board via SD card (software update for motherboard; something different from normal FW) – this SD Card Image you find on manufacturer’s pages. After flashing SD card image, the miner resets to factory settings, so as second step you must upload firmware to the miner (via IP interface or SD card)

If the miner has all 3 hashboards loaded but power is zero (no temperatures, or shows empty status page / respectively power jumps only briefly and then immediately drops):

• on 90% it’s the power supply blown (good news, because blown “only” power supply is the smallest problem)

Before installing the miner, please check it thoroughly, including individual hashboards. If any cooler has loosened or completely fallen off during transport, return the damaged board to our center. NOTE: using a faulty board can cause further damage. All PCI-e connectors on the motherboard are required to connect to the power supply. In most cases, each hashboard has three PCI-e connectors. You can use one power supply to power multiple hashboards, but DO NOT TRY to power one board with more than one power supply. (Attempting to power one board with more than one power supply could cause irreparable damage to the product.) Our recommendation is to use a high-power power supply for powering this device, based on its specific model, hashrate and ambient temperature etc.

Make sure ventilation openings are not blocked.

Leave free space around the miner. Recommended ambient temperature for the miner is 25 – 40 ° C, while humidity requirement is 5% – 95%. At lower temperatures be careful to prevent condensation.

If the miner emits a strange smell, sound or smoke, immediately unplug the network plug and contact the service center

Under no circumstances hit the product or let it fall to the ground.

Make sure all cables are firmly connected and properly aligned.

Power the control board first and then the hashboard. (This is because the fans are powered by the control board, it is recommended to power the hashboard at least 1 minute after turning on the control board.).

The outlet must be installed near the device and must be easily accessible.

The device must not be directly connected to primary power and must obtain power from a safety isolation transformer with double or reinforced insulation or equivalent device (only for device without power supply).

The server uses DHCP protocol to obtain IP address. Default login name and password are according to miner type (see “how to connect and start miner”)

Kernel log is a text description of what the miner does (turns on, checks fans, checks power supply voltage, then temperatures ..)
