νUPS On/Off
νDo Self Test – UPS verifies proper system operation by briefly powering the attached load from battery.
νSimulate Power Fail – causes UPS signaling port to immediately indicate that the AC line has failed. This may initiate an orderly server shutdown sequence if the appropriate cable and software drivers are used.
νGraceful Reboot – initiates an orderly server shutdown and re- start sequence if the appropriate cable and software drivers are used. The sequence is:
1.The UPS signaling port indicates that the AC line has failed and that the UPS battery is low. (Server will quickly begin shutdown if so configured.)
2.After the Low Battery Duration time plus the Shutdown De- lay time (user settable parameters in Setup:Shutdown) the UPS will turn off for the Return Delay time (user settable pa- rameter in Setup:Shutdown) then come back on unless: (1) the input AC line voltage is out of tolerance or (2) the battery capacity is below the Return Battery Capacity (user settable parameter in Setup:Shutdown).
νGraceful Turn Off – same as Graceful Reboot above except that the attached load remains off until turned on by the user via the
Control:Turn Load ON command.
νStart/Stop Runtime Calibration – causes UPS to run on battery until the battery(s) is(are) discharged to approximately 25% of capacity. Data recorded during this time improves the accuracy of the Runtime estimate which the UPS reports in the Status screen. Recommended testing interval: once per month.
νUPS into/out of Bypass (Matrix and Symmetra only) — When bypassed, power to the attached load is being supplied through the UPS’s filtering and surge suppression circuits directly. The UPS will not power the loadfrom the battery in the event of a power failure. This is generally used during maintenance on modular UPSs.
