LED diagnostic guidance

Your product has diagnostic LEDs which can be used to identify the unit’s status and to help troubleshoot any potential issues that may occur.

The following section provides two basic examples of how to interpret the LED diagnostic patterns included in this publication.

Example solid LED diagnostic pattern:

  1. LED ON — Indicates the color assigned to the unit’s diagnostic LED, and confirms that the diagnostic LED is active (switched on).

  2. LED OFF — Indicates that the unit’s diagnostic LED is inactive (switched off).

  3. Diagnostic pattern — Indicates a diagnostic pattern based on the number and duration of peaks (indicating LED is switched on) and troughs (indicating LED is switched off) generated within the duration of the diagnostic pattern. In the example shown, a continuous peak occurs, indicating that the LED is permanently on.

Example flashing LED diagnostic pattern:

  1. LED ON — Indicates the color assigned to the unit’s diagnostic LED, and confirms that the diagnostic LED is active (switched on).

  2. LED OFF — Indicates that the unit’s diagnostic LED is inactive (switched off).

  3. Diagnostic pattern — Indicates a diagnostic pattern based on the number and duration of peaks (indicating LED is switched on) and troughs (indicating LED is switched off) generated within the duration of the diagnostic pattern. In the example shown, a peak followed by a trough occurs and then repeats again, indicating that the LED flashes twice within a period of one second.

  4. Diagnostic pattern duration — Indicates the total duration of the diagnostic pattern.

  5. Diagnostic pattern flash total — Indicates the total number of flashes that occur within the diagnostic pattern.
