Periods of interoperability of sideband buses prevent effective management of managed devices by a remote access controller. Embodiments avoid periods of inoperability of sideband buses and recover the sideband bus without resetting the managed devices or the IHS (Information Handling System). The remote access controller configures timer and transmits the timer to a managed device. The managed device monitors the sideband for messages for the remote access controller. If no messages are received before expiration of the timer, the managed device resets its sideband bus endpoint, without resetting the managed device.
