The bus includes a positive bus and a negative bus. The three-level inverter circuit includes a first bus capacitor and a second bus capacitor. The first bus capacitor is connected between the positive bus and a bus neutral point, and the second bus capacitor is connected between the negative bus and the bus neutral point. The DC-DC conversion circuit includes a first conversion circuit and a second conversion circuit, an input terminal of the first conversion circuit is connected in parallel to the first bus capacitor, and an input terminal of the second conversion circuit is connected in parallel to the second bus capacitor.

An information handling system includes multiple data ports, a memory, and a processor. Each of the data ports enables a separate communication link of a plurality of communication links for the information handling system. The memory stores data to indicate whether the information handling system supports bridge assurance on each of the communication links. In response to the bridge assurance being supported in the information handling system, the processor provides a message across a first link of the communication links. The message indicates that bridge assurance is supported in the information handling system. The processor also determines whether an acknowledgement message has been received. In response to the acknowledgement message being received, the processor enables the bridge assurance on the first link.
