The Grid Manager uses the following icons to show the health of each grid node. The icons indicate whether nodes are connected to the grid and show if any alarms are active on the node.
Icon | Color | Node state | Alarm severity | Meaning |
---|---|---|---|---|
![]() |
Green | Connected | Normal | The node is functioning normally. It is connected to the grid and there are no alarms. |
![]() |
Yellow | Connected | Notice | The node is connected to the grid, but an unusual condition exists that does not affect normal operations. |
![]() |
Light Orange | Connected | Minor | The node is connected to the grid, but an abnormal condition exists that could affect operation in the future. You should investigate to prevent escalation. |
![]() |
Dark Orange | Connected | Major | The node is connected to the grid, but an abnormal condition exists that currently affects operation. This requires prompt attention to prevent escalation. |
![]() |
Red | Connected | Critical | The node is connected to the grid, but an abnormal condition exists that has stopped normal operations. You should address the issue immediately. |
![]() |
Gray | Disconnected | Administratively Down | The node is not connected to the grid for an expected reason. For example, the node, or services on the node, has been gracefully shut down, the node is rebooting, or the software is being upgraded. |
![]() |
Blue | Disconnected | Unknown | The node is not connected to the grid, and the situation requires immediate attention. For example, the network connection between nodes has been lost or the power is down. This is the most severe condition. |
