Article Summary

The Skylight sensor: control provides alarm functions to monitor and report on the status of the unit, of the traffic performance and of other components.

Setting General Alarms


To set up general alarms

  1. Access the page System ▶ Alarm ▶ General.

  2. Complete the required fields, then click Apply.


    Note: If you modify the alarm settings and then decide to discard those changes, click the Reset button to revert to the last set of saved settings. However, once you have clicked Apply, previous settings can only be restored manually.

For more information on specific parameters, refer to the following table.

Alarm Settings (System ▶ Alarm ▶ General)

  1. Click the Number of the alarm that you want to edit.

    The Alarm Configuration page appears.

  2. Complete the required fields, then click Apply.


Note: If you modify an alarm's configuration, then decide to discard those changes, click Reset to revert to the last set of saved configuration values. Once you click Apply, however, you must manually restore the previous configuration values.

For more information on specific parameters, refer to the following table.

  • AA: Module number (1-99)
  • BBBB: Instance number (0000-9999).
  • CC: Error number (01-99)

A module number is assigned for each alarm in the system.

EnableIndicates whether the alarm is enabled (true) or disabled (false). If enabled, alarms are reported.
SeverityThe severity of the alarm.
  • Informational: No effect on service. Provides status information.
  • Minor: An error condition has occurred that does not seriously affect system functionality.
  • Major: A serious degradation of service or hardware malfunction has occurred which requires immediate attention to restore system functionality.
  • Critical: A service affecting condition has occurred that requires immediate corrective action.
Service AffectingAlarms may be displayed as true for service affecting or as false for non-service affecting.
Device NameName of the device against which the alarm is raised.
DescriptionTextual description of the alarm. The description is displayed in the Show ▶ Alarm page.

Viewing Alarms

This article explains how to view alarms and provides a list of all supported alarms and their default description.

To view the status of an alarm

    Viewing Chassis Alarms

    To view the status of remote devices chassis-related alarms and information, including power supplies, temperature sensors and fan status

    1. Access the page System ▶ Alarm ▶ Chassis.
      The remote devices chassis' status is displayed.

    For more information on specific parameters, refer to the following table.

    Remote device chassis status and alarms (System ▶ Alarm ▶ Chassis)

    Power Supplies

    ParameterDescription
    Power Feed A and Power Feed BThe status of the power sources for a DC Powered unit: Feed A and Feed B.
    • The Feed B indicator is always green when power to the unit is connected. The Feed B indicator DOES NOT indicate that a feed is connected to the Feed B input.
    • The DC Feed A and DC Feed B lights indicate which DC feeds are in use.
    • A green light indicates that the power source is connected and is operating normally.
    • A red light indicates that the power source is not connected or is not operating normally.

    Temperature Sensors

    ParameterDescription
    PHY, CPU and FPGA Temperature SensorsThe following information is provided for each sensor (PHY, CPU and FPGA):
    • Status: Either Present or Not Present
    • Alarm: Set to In Alarm (if an alarm has been triggered) or None
    • Temperature: The most recent temperature detected by the sensor, expressed in Celsius
    • High-Temperature Warning: The temperature that triggers an overheating warning, expressed in Celsius
    • High-Temperature Alarm: The temperature that triggers an overheating alarm, expressed in Celsius
    • Low Temperature Warning: The temperature that triggers a low temperature warning, expressed in Celsius
    • Low-Temperature Alarm: The temperature that triggers a low-temperature alarm, expressed in Celsius

    For details on any alarms or warnings, access the page Show ▶ Alarm.

    Fan Monitors

    ParameterDescription
    Fan 1 and Fan 2For each fan on the unit (identified as 1 or 2), the following information is provided:

    Status:

    • Present: The fan is connected.
    • Not Present: The fan is not connected.

    Alarm:

    • In Alarm: An alarm has been triggered for this fan.
    • None: No alarm has been triggered for this fan.

    Speed:

    • This the number of rotations per minute made by the fan, expressed in RPM.

    The following threshold information is provided for each fan:

    • Fan-Stall Alarm: This is the fan speed at which the fan stall alarm is triggered, indicating that the fan is no longer functioning. Expressed in RPM.
    • Fan-Aging Warning: This is the fan speed at which the fan aging warning is triggered, indicating that the fan is no longer functioning optimally. Expressed in RPM. Fan-Aging Alarm: This is the fan speed at which the fan aging alarm is triggered. Expressed in RPM.

    For details on any alarms or warnings, access the page Show ▶ Alarm.

    Dying Gasp Alarm

    The Dying Gasp feature is supported on Skylight sensor: module 1G only. The Skylight sensor: SFP compute 1G does not support Dying Gasp since it relies on the SFP host to generate the Dying Gasp.

    Before losing power, at least three Dying Gasp layer-2 defined in 802.ah are sent on both the UNI and NNI ports. Also, a proprietary Dying Gasp message is sent on the management connection from the NNI port towards Skylight sensor: control to raise the Dying Gasp alarms. The Dying Gasp alarm is cleared in Skylight sensor: control when the device is linked.
