At a certain sit, two safety disks of the S5600T have lighted red all the while.
1. Repalce the hard disk, it will display the same fault again a soon later.
2. After confirming that the cascading board and link are both well, through the research locating on site, we doubt that it’s the dust onsite may influence the backend connector of the hard disk.
3. Clean the connector with alcohol, and plug into the enclosure, take the pressure test, the hard disk recovers to be normal, and there isn’t any bit error. Then we can confirm the cause of the fault is the dust, and it pollutes the surface of the high-speed signal transmitting medium.
The possible reasons:
1. The hard disk fault;
2. The cascading board fault;
3. The backend link fault;
4. There is dusty on site, it may impact the internal circuit.
The environment on site takes a high influence on the device, we remind the customer to maintain it carefully, and avoid suffering loss.
