Detailed forensic information is available after system or module failures. The BMC Power-Up Error Log function provides detailed information about history of failures that may have occurred during power-up sequences. Log information includes e.g. error number, flags, restart event, power cycles, boot count, status, CPU temperature and board temperature. Moreover minimum and maximum temperature of the CPU and system is available, as well as HDD S.M.A.R.T information- all of which can be used to analyze system or module failure in detail.

SEMA is available for Linux and Windows operating systems and for various HW platforms.

Graphical User Interface

The SEMA GUI graphical interface is available for Windows and Linux operating systems. To get started, simply run semagui.exe (Windows) or SEMA_GUI.sh (Linux). In Windows, the shortcut for SEMA GUI will be located on the desktop. In Linux, the SEMA GUI files will be located at /usr/local/SEMA/bin. You can execute the GUI by using SEMA_GUI.sh

There are four views that can be selected at the right side of the GUI: SEMA Functions, System Information, Firmware Update and BMC Error Log. In the SEMA Functions view the following tabs that can be selected: System Overview, System Health, User Flash Memory, Hardware Controls, Hardware Monitor, I2C Bus, GPIO, 1-Wire and ADC (A/D conversion). In the System Information view tabs for CPU and Memory Information, Network Information and Hard Disk and S.M.A.R.T Information are available. Users can update the BIOS or BMC firmware in the Firmware Updates view and users can observe BMC’s power-up sequence error logs in the BMC Error Log view.

Command Line Interface

The SEMA command line interface is available for both Linux and Windows versions. To use it please open a Linux Console or the Windows Command Line tool, respectively. For a description of the supported SEMA command line options, refer to the following sections.
