  • Improvement to resiliency features (SRX1600, SRX2300, SRX4120, and SRX4300)—We've made multiple improvements to resiliency features on the listed devices, including:

    • Support for a minimum of three failed readings before triggering an alarm to improve reliability
    • Alarms for voltage output, current, and fan faults for AC and DC power supply units (PSUs)
    • Range check for all sensors to ensure that only valid sensor values can trigger alarms
    • Availability of debug information to triage root cause for alarms, in addition to monitoring component health, triggering alarms and log messages. Recovery is not supported.
    • Alarm for mismatching firmware when the firmware installed does not follow the minimum requirements and recommendations
