A first service processor of the first device operates as a master baseboard management controller of the server board, and monitors a communication channel for alive messages from a plurality service processors. A second service processor operates as a secondary baseboard management controller, and sets a second timer to a first value. In response to a determination that the second timer has expired based on a first value: the second service processor to start a switchover process, and to set the second timer to a second value based on an alive message period. In response to a primary alive message not being received from the first service processor prior to the second timer expiring based on the second value, the second service processor to reset first service processor and to operate as the master baseboard management controller.
