Understanding node icons

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 checkmark icon Green Connected Normal The node is functioning normally. It is connected to the grid and there are no alarms.
yellow square icon Yellow Connected Notice The node is connected to the grid, but an unusual condition exists that does not affect normal operations.
light orange diamond icon 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 diamond icon 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 x icon 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 questionmark icon 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 question mark icon 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.
