Intelligent Chassis Management Bus (ICMB) Controller
The ICMB Controller resides on the Legacy I/O Board. It serves as a bridge between the
internal Intelligent Platform Management Bus (IPMB) and the external Intelligent Chassis
Management Bus (ICMB). The internal IPMB transports server management information
within a system, and the external ICMB transports server management information between
various chassis in a server(s) and peripherals cluster configuration.
Hot Swap Controller (HSC)
The Hot Swap Controller (HSC) resides on the Power Distribution Board (T-Docking). The primary
functions of the HSC are as follows:
• Implements the SAF-TE command set
• Controls the fault lights
