Why is the status of the Antminer ASIC chip displayed as X?

Fault: After running for a period of time, the hash board chip is missing or the ASIC chip status shows X.

For example, a working D3 hash board has 60 ASIC chips. The following figure shows that hash board No. 1 is missing chip, No. 2 is normal, and No. 3 shows X.

Troubleshooting steps:

1. Replace with a well-known PSU for testing.

2. Confirm that the miner is well-grounded.

3. Confirm the network is normal.

1 Network => 2 Diagnosis => 3 Enter the pool layer => 4 Ping => 5 Check the result

Packet loss rate: 0% is normal.

Delay: The average delay is less than 100ms, and the deviation between the maximum delay and the average delay is not large, which is normal. (Take Antpool as an example: ping stratum.antpool.com)

4. Confirm that the miner is operating in a normal temperature environment and there is no dust accumulation or other debris attached.
