Abstract: Embodiments generally relate to a universal debug design which involves integrating a debug controller and a debug card with display together into a single debug design. Debug codes, such as power-on self-test (POST) codes and other error codes, are generated by various subsystems of a server-related system. The codes are transmitted to a controller, which stores the codes in memory. In some embodiments, a multiplexer outputs one debug code from the multitude of received codes, based on a user or event selecting which desired debug code should be displayed. In some embodiments, a decoder converts and sends the LED display signals to a debug card, which displays the debug code on a 7-segment LED display.

Abstract: In some implementations, service controllers of a computing device are associated with various disparate components of the computing device, and in response to a command issued to any one of the components, the service controllers may communicate with each other in order to transmit data responsive to the command. For example, a computing device may comprise a Baseboard Management Controller (BMC) and a Serial Attached SCSI Expander card (SAS Expander). The BMC of computing device receives a remote command requesting status of a hard drive coupled to the computing device, and the BMC communicates the command to the SAS Expander, for example over a system bus of the computing device. The SAS Expander retrieves a response to the command and communicates the response to the BMC, which then transmits the response to the remote site.
