FIELD: machine building.
SUBSTANCE: group of inventions relates to rack with automatic recovery function. For this purpose, rack comprises control module and plurality of units. Control module comprises rack monitoring controller (RMC), and each of plurality of units contains board monitoring controller (BMC). RMC interacts with BMC through plurality of standard communication channels, respectively, wherein RMC controls units and transmits necessary to them data via BMC. In case of response signal loss from one of BMC RMC resends same signal to not responded BMC. If repeated transmission threshold value is achieved, then RMC sends control signal to responded BMC reset output directly over GPIO channel, to make reboot of not responded BMC.
EFFECT: technical result is providing board monitoring controller (BMC) reboot for initial state recovery in absence of normal interaction rack monitoring controller (RMC) in rack with BMC in rack unit.
