RE: PowerEdge SC1430 lights 1&2 blink amber power light
According to your system documentation, the blinking amber lights 1&2 is due to System Board Regulator failure in which; "A power failure has been detected in one of the onboard system board regulators. This could be caused by a failed system board component or by a plug-in device creating a short on a regulated power rail. (PS_ON asserted, PS_PWRGOOD asserted, SYS_PWRGOOD de-asserted)"
In order to rule out the system board failure, remove any attached USB devices and use minimum to POST components below:
Processor (with heatsink) in socket 1
One stick of memory in slot 1
Control panel (to turn on system)
If the blinking lights persist, replace the system board.
