ONT Power

Depending on the ONT type, there are three different Power tabs that may be displayed.

Use the following procedure to view or edit the ONT Power parameters of ONTs that support Power over Ethernet (PoE):

  1. If the ONT supports Power over Ethernet (PoE), click the Power tab. The Power dialog is displayed.

  2. Refer to the table below for descriptions of the contents of each field in the Power over Ethernet Section of the Power tab.

  3. If the ONT supports Power Shedding, click the Power tab. Refer to the table below for descriptions of the contents of each field in the ONT Property – Power Tab.

  4. Click the Apply button to save any ONT provisioning updates.
  5. A confirmation message is displayed. Click the OK button.

  6. Refer to the table below for descriptions of the contents of each field in the Power over Ethernet

    Section of the Power tab.

    Note: The Power tab displays differently depending on the selected ONT type.

     

    Field

    Description

    Config

    Alarm Threshold

    The Alarm Threshold defines the percentage of the Nominal PoE power being allocated and will trigger a threshold crossing alert for the ONT level. This informs the user when the requested PoE power is near its maximum value. The Alarm Threshold value is 2 digits. This value is set through the ONT Template.

    External Power Supply

    The External Power supply defines the power that is available when the ONT has a BBU and is on battery power. Enter a value, in watts, for the selected ONT.

    Note 1: If the ONT Type is set to ONT120, ONT140, or ONT709, set the Power Supply to 50 watts for PoE ONTs supported by a Battery Backup Unit (BBU), or 75 watts (default) for PoE ONTs supported by AC power.

    Note 2: If the ONT Type is set to ONT728 or ONT729, set the Power Supply to 450 watts (default) if the ONT power is being supported by an Uninterruptable Power Source (UPS), or 450 watts (default) if power is provided from a direct AC source.

    Battery Power Supply

    If configured with Battery Power Supply)

    Indicates that Battery Power Supply is available. The BBU Power value is 2 digits Range: Depends on ONT type.

    Watts: For ONT120 & ONT709 (75 Watts)

    Enable PoE Alarms

    Enables the generation of PoE Threshold crossing alarm. Values are Enable or Disable. Default is Enable.

    Status

    Operation Status

    Defines whether the PoE power circuit is operating normally. Values are: Up, Down or Faulty. Faulty indicates a total power draw that is exceeded or a PoE hardware issue.

    Nominal Power

    Defines the maximum PoE power that is available to the ONT PoE circuit. External power minus ONT base power and losses equals Nominal PoE Power.

    Allocated Power

    Defines the total of all PoE power requested from attached PoE devices on all ONT ports.

    Delivered Power

    Defines the current number of Watts being delivered to devices via PoE.

    Power Status

    AC Power Status

    Displays the power status of the AC power supply. Values are: OK – On AC power

    Fail – AC power has failed.

    Unknown – Power status not known.

    Battery Status

    (if configured with a BBU)

    Provides current ONT Backup Battery Unit status. Supports reporting of: OK – Battery power available and batteries okay.

    BBU missing – Battery is missing

    BBU HW fail – Battery power has failed

    BBU low – Battery power at low power threshold.
  7. If the ONT supports Power Shedding, click the Power tab. Refer to the table below for descriptions of the contents of each field in the ONT Property – Power Tab.
     

    Field

    Description

    Config

    Restore power timer reset interval (zero means disabled)

    Range is 0 to 64980 seconds. Default is 30 seconds.

    Data class shedding interval (zero means disabled)

    Range is 0 t0 64980 seconds. Default is 30 seconds.

    Video overlay class shedding interval (zero means disabled)

    Range is 0 to 64980 seconds. Default is 30 seconds.

    Status

    Powered

    Status

    AC Power Status

    Displays the power status of the AC power supply. Values are: OK – On AC power

    Fail – AC power has failed. If a BBU is configured, see Battery Status.

    Battery Status

    (if configured with a BBU)

    Provides current ONT Backup Battery Unit status. Supports reporting of: OK – Battery power available and batteries okay.

    BBU missing – Battery is missing

    BBU HW fail – Battery power has failed

    BBU low – Battery power at low power threshold.
  8. If the ONT is a desktop ONT capable of a Battery Backup Unit (BBU), click the Power tab. Refer to the table below for descriptions of the contents of each field in the ONT Property – Power Tab.
     

    Field

    Description

    Power Status

    AC Power Status

    Displays the power status of the AC power supply. Values are: OK – On AC power

    Fail – AC power has failed. If a BBU is configured, see Battery Status.

    Battery Status

    (if the ONT is configured with a BBU)

    Provides current ONT Backup Battery Unit status. Supports reporting of: OK – Battery power available and batteries working
