Alarm Indicator Colors
From the Common Tree, the highest priority alarm present can be determined by examining the OLT icon color (
). The color indicates the most severe alarm (MSA) present on that OLT. Table 1 lists the colors that can appear and a description for each color.
Table 1: Common Tree - Alarm Indicator Colors and Descriptions
| Light Emitting Diode (LED) Color | Description |
| Grey | OLT is disabled. |
| Green | OLT is configured and no alarms are present. |
| Red | OLT has an active critical alarm. |
| Orange | OLT has an active major alarm (no critical alarms present). |
| Yellow | OLT has an active minor alarm (no critical or major alarms present). |
| Cyan | OLT has an active warning (no critical, major, or minor alarms present). |
| Blue | The OLT has reported a value of "Indeterminate" for the MSA. This means that there may be alarms on this card, but the severity assigned to the alarms are "indeterminate" (refer to Alarm Color Codes and Status). |
In addition, from the Common Tree, the highest priority alarm present on a PON can be determined by examining the Eqpt icon color (). The color indicates the most severe alarm (MSA) present on that piece of Eqpt. Table 2 lists the colors that can appear and a description for each color.
