After power failure, the S7-410-5H RACK 1 shows the EXT F and BUS F leds on, attached are the Diagnostic Buffer for both Racks. The IM153-2 redundant modules shows BUSF1 and BUF2 leds on. I see in several IM153-2 both channels with BUSF1 and BUSF2 leds on too. The S7-410 5H has EXT F fault it means the failure is in the S7-300 hardware, can you support me in order to find the problem in the HW structure.
