It is builds on the basic +functionality of the BMC Theseus and contains several new features and +enhancements. It can monitor up to 4 voltages, 16 temperatures and +8 fans. It also contains an integrated watchdog which is currently +implemented in this driver. + +The ``pwmX_auto_channels_temp`` attributes show which temperature sensor +is currently driving which fan channel. This value might dynamically change +during runtime depending on the temperature sensor selected by +the fan control circuit. + +The 4 voltages require a board-specific multiplier, since the BMC can +only measure voltages up to 3.3V and thus relies on voltage dividers. +Consult your motherboard manual for details. + +To clear a temperature or fan alarm, execute the following command with the +correct path to the alarm file:: + + echo 0 >XXXX_alarm + +Specifications of the chip can be found at the `Kontron FTP Server <http://ftp.kontron.com/>`_ (username = "anonymous", no password required) +under the following path: + + /Services/Software_Tools/Linux_SystemMonitoring_Watchdog_GPIO/BMC-Teutates_Specification_V1.21.pdf |
