Till input power from PSU1 off (PSU2) off (PSU2) is removed. 5.2 GRAPHICAL USER INTERFACE The Bel Power Solutions provides with its “I2C Utility” a Windows® XP/Vista/Win7 compatible graphical user interface allowing the programming and monitoring of the SPDFCBK-15G / SPDFCBK-16G Front-End. The utility can be downloaded on www.belpowersolutions.com and supports both the PSMI and PMBus™ protocols. The GUI allows automatic discovery of the units connected to the communication bus and will show them in the navigation tree. In the monitoring view the power supply can be controlled and monitored. If the GUI is used in conjunction with the SPDFCBK-15G / SPDFCBK-16G Evaluation Kit it is also possible to control the PSON pin(s) of the power supply. Further there is a button to disable the internal fan for approximately 5 seconds (not implemented yet). This allows the user to take input power measurements without fan consumptions to check efficiency compliance to the Climate Saver Computing Platinum specification. tech.support@psbel.com Input OK/H PWOK/H PSON/L PRESENT/L PS KILL PWR OK FAIL

SPDFCBK-15G / SPDFCBK-16G 5 The monitoring screen also allows to enable the hot-standby mode on the power supply. The mode status is monitored and by changing the load current it can be monitored when the power supply is being disabled for further energy savings. This obviously requires 2 power supplies being operated as a redundant system (like the evaluation kit). NOTE: The user of the GUI needs to ensure that only one of the power supplies have the hot-standby mode enabled. Approved to the latest edition of the following standards: UL/CSA60950-1, IEC60950-1 and EN60950-1.
