Symptom(s):
Some hard drive LED activity will not work when using our Serial ATA (SATA) backplanes.
Cause:
The Hard drive LED activity on our SATA backplanes is NOT only controlled by the GEM424 controller. They can also be driven by the drives themselves using pin 11 on the connector. Therefore, if a system has newer SATA drives that support this Drive Activity LED pin, the backplane LEDs will support drive activity regardless of what SATA controller is used.
Solution:
Suggest customer use newer SATA drives that support the Drive Activity LED pin.
Note:
If customer uses an older SATA drive that not support the drive activity LED pin 11. The SATA backplane LED activity will not work while the data is read or written. This behavior will not affect the system operation.
