I buy two pieces on Ebay , i think it's you sell IT.

I found in the miner some fan parts, a connector cut from a Fan , in the two pieces , when you move it your heard moving.

Some cards have missing plastic retention for the radiator , small white pieces to maintain radiator to the PCB , i found in the miner this piece , i need to remove it before start the miner.

I resume , fan conncector and plastic retention in the miner, need to remove it before start miner.

The miner dont go far 400 mhs , i use antminer L3+ and a Innosillicon , in the same environnement, run about 600 - 640 Mhs /second , with fan at 60%

The firmware is 2.8.0 and dont show the temperature of the PCB.

Hi Cedric,

I dont see you among my sales. But nonetheless i will try to help, although i would suggest trying to resolve this through EBAY. Its better to keep it official.

The plastic parts that seem so be around the miner must be due to damage during transport. Did you see any damage on the outside of the package?

The temperature not showing is normal, its the same for all BW L21 miners.

The 400MHS hashrate may be for due to shipping damage. The miner should state 550 MHS in the miners interface.

Please use the following steps:
1. remove and reconnect all PCIE power cables to the miner. Restart miner. If there is no change, please proceed to step 2.
2. Swich PSU with the other miner. If there is no change, please proceed to step 3.
3. Sometimes during trasport some clients have found that the boards had moved. Please open the miner and push the boards down into their slots.

Let me know if the problem has resolved.
