Just like many other users, My DL4100 stopped working with same symptoms of flashing blue LEDs, blank display and restarting by itself every few minutes. It has 4 x 6TB in RAID 5 configuration.
1- Is there a way to manually re-flash the boot memory or upload the latest WD image?
2- Is there a replacement board for the DL4100?
3- What is the use / purpose of the 4-pin connector in the main board located near the cooling fan connector?
