Hot Swap Controller (HSC)
The Hot Swap Controller (HSC) resides on the T-docking board. The primary
functions of the HSC are as follows:
• Implements the SAF-TE command set
• Controls the fault lights
• Provides a path for management information through the SCSI
• Retrieves drive fault status, backplane temperature, and fan failure information
through IPMB
• Queries the status of the power distribution board by retrieving information from
the BMC through the IPMB
• Controls drive power-on and power-down, facilitating hot-swapping.
Chassis Bridge Controller (CBC)
The CBC 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 cluster configuration that can contain
multiple servers and peripherals.
