# Turn NGFW Engines online

You can turn engines in the offline state online through the right-click menu.

##

When engines are in the offline state, the status icon is blue and the status text reads offline. You can turn engines online if there are no configuration issues that would prevent the node or cluster from operating normally. Typical issues that can prevent a node from going online include policy issues, automatic tests failing, or heartbeat connection problems between nodes in clusters.

Note: You might also be able to give commands to nodes in the unknown state (gray icon), but you might not see a change of status. Because the actual operating status is not available, the node might already be online. In this case, you might receive an error if you try to command the node online.
Note: If the cluster is set to standby mode, only one node at a time can be online. Commanding a standby node online switches the current online node to standby.
