I recently rack mounted my Supermicro JBOD SC847, and it looks like it blew a fuse/breaker.
Power LED does not come on any longer, I have +5VDC & +12VDC on drive cables but no activity on the drives, fans are fully functional, it looks like there's a blown fuse/breaker after the power supply, or damaged board, has anyone seen this issue before, desperately need help in repairing or replacing the component causing the issue. SAS2-847EL2, Also can anyone tell me how to cascade the front controller to the back one, I's like to see all drives with one cable, currently it's split into two independent controllers.. Thank you very much for any assistance, I hope someone has better diagrams or drawings than the manual.
