    Cooling System

    High efficiency cooling system-4x Heavy duty fans with Optimal Fan Speed Control, for less power and ensure a stable environment and availability 24/7.

    System Health Monitoring

    The system has an onboard Baseboard Management Controller (BMC)
    chip that supports system health monitoring.

    Onboard Voltage Monitors

    The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage becomes unstable, it will give a warning or send an error message to the IPMI WebGUI and IPMIView. Real time readings of these voltage levels are all displayed in IPMI.

    Fan Status Monitor with Firmware Control

    The system health monitor embedded in the BMC chip can check the RPM status of the cooling fans. The CPU and chassis fans are controlled via lPMI.

    Environmental Temperature Control

    System Health sensors in the BMC monitor the temperatures and voltage settings of onboard processors and the system in real time via the IPMI interface. Whenever the temperature of the CPU or the system exceeds a user-defined threshold, system/CPU cooling fans will be turned on to prevent the CPU or the system from overheating.

    System Resource Alert

    This feature is available when used with SuperDoctor 5. SuperDoctor 5 is used to notify the user of certain system events. For example, you can configure SuperDoctor 5 to provide you with warnings when the system temperature, CPU temperatures, voltages and fan speeds go beyond a predefined range3.
