For rails that are off due to fault response and ON_OFF_CONFIG set to AUTO, the only way to power them on again is to enable the re-sequence option at its fault response. With the re-sequence option, the faulted rail plus its fault shutdown slaves is re-sequenced when the retry account of the faulted rail is exhausted. The re-sequencing times and intervals are set through Global Configuration → Misc_config as shown in Figure 22.
