Replacement tutorial for IceRiver KS3L control board

The Iceriver KS3L control board, equipped with a Xilinx XC7Z010 CPU chip and 1*4P fan interfaces, is primarily responsible for collecting and processing data returned by the hash boards. Precise regulation ensures efficient communication between components, thereby achieving stable operation of the miner.

If the Iceriver KS3L miner experiences issues such as abnormal hash rates, non-operational fans, non-illuminated or red-lit indicator lights, inability to find the IP, failure to access the miner's backend or drop chain. These may be caused by the malfunction of the control board. At this time, it is recommended that the first replacement be with a new spare board to restore the miner's operation quickly, followed by troubleshooting the original control board to minimize losses.

Detailed replacing steps for Iceriver KS3L miner control board:

1. Turn off the power, then disconnect the power cord from the socket.

2. Remove the protective cover plates on the top and side of the control board, and then unplug all connected cables from the motherboard.

3. Gently push the control board toward the air inlet to remove it.

4. Inspect the new Iceriver KS3L spare control board for any visible damage and ensure suitable welding of electronic components. Align it with the card slot on top of the chassis, gently push it into place, finally reconnect the cables.

5. Install the protective cover plates of the control board to complete the replacement.

6. Power on the miner, then scan the IP to access the backend management interface to check its operational status.

In the rapidly evolving world of cryptocurrency mining, every second of downtime can result in significant economic losses. Therefore, mining farm managers should maintain an adequate inventory of critical components such as control boards to enable prompt replacements in emergencies, ensuring continuous operation of miners and stable returns for investors.
