Power Monitor
(ONS 15454 and ONS 15600 only) Use the Power Monitor subtab to provision the power supply alarm thresholds. The threshold crossings are provisionable in the range –40.5 VDC to –72.0 VDC in 0.5 VDC increments. To see proper alarmable behavior, set the values based on the input voltage going into the system. Each threshold applies to an alarm with the same name. For example, if the Extreme High Battery Voltage (EHIBATVG) threshold is set to –56.5 VDC, the EHIBATVG alarm is raised when that threshold is crossed. The alarm severity depends on whether one or both ONS node power supplies (PWR-A and PWR-B) have alarms. If only one power supply has an alarm, the alarm is Minor/Non-Service-Affecting (NSA). If both power supplies have an alarm, one of them is Major/Service-Affecting (SA).
