Radial IPMB bus topology

The FortiGate-5144C backplane includes a redundant dual star radial IPMB bus for higher reliability. Each shelf
manager provides 14 unique IPMB0-A and 14 unique IPMB0-B links to the 14 chassis slots. This means 28 IPMB
channels per shelf manager. The radial topology is shown below.
