Identifying a Faulty Hash Board: In-Depth Manual

Welcome to WisdoMining! If you suspect damage to your hash board, follow these steps to pinpoint potential issues and determine the best course of action.

Step 1: Shut Down Your Antminer
Ensure your Antminer is completely powered off before beginning the inspection process. Disconnect it from the power source for safety during evaluation.

Step 2: Understanding Hash Board Identification
To accurately pinpoint the problematic hash board, it is crucial to comprehend the numbering system used in the Antminer's logs and control board.

• Log File Numbering: Hash boards are typically numbered starting from zero in the log files. For instance, the first hash board is labeled "Chain 0," the second board is "Chain 1," and so forth.
• Control Board Numbering: Hash boards on the physical control board may be marked or numbered. Take note of these numbers during your visual examination.

Step 3: Examination of Log Files for Specific Details
Consult the Antminer's log files to gather specific information about the condition of each hash board. Look for error messages, irregularities, or warnings that can help identify the problematic board.

Step 4: Visual Check-up

• Burn Marks: Inspect the hash board for any visible burn marks or discoloration, indicating potential overheating or electrical issues.
• Charring: Look for signs of charring or melted areas on the board, which may indicate serious electrical problems.
• Connectors: Verify the integrity of connectors, ensuring they are not bent or damaged.

Step 5: Linking Visual Inspection with Log Files
Connect the observations from the visual inspection with the data from the log files. Seek out patterns that link specific issues with particular hash boards.

Step 6: Smell Test
Use your sense of smell to detect any unusual odors coming from the hash board. A burnt or smoky scent could signal electrical issues or components that have overheated.

Step 7: Optional Multimeter Examination
If you have a multimeter and feel confident using it, conduct basic electrical checks:

• Continuity Test: Verify continuity on key pathways to identify any breaks in the circuit.
• Voltage Check: Measure the voltage at specific points to ensure it aligns with expected values.

Step 8: Reassembling and Powering Up
After the inspection, carefully reassemble your Antminer. Power it on and observe for any abnormal sounds or LED indicators.

Step 9: Marking and Identifying the Faulty Hash Board
Based on the visual inspection, log file analysis, and any additional tests conducted, mark and identify the specific hash board that requires attention. Make a note of any unique identifiers or serial numbers associated with the faulty board.

Step 10: Warranty Considerations
If your Antminer is still covered by the manufacturer's warranty, it is advised to contact the official service center. Be aware that this process may take some time, usually not less than a month.

Step 11: Swift Repair at WisdoMining
For a quicker solution, you can send the faulty board to WisdoMining. However, be aware that this choice forfeits any remaining warranty from the manufacturer.
