Wait few seconds and your node will be removed from the table.
  -To replace a failed node using the UI you have to check if the Node is failed using `Has node failed` command. If Controller status says `NodeFailed` the node can be replaced, if not controller will say `NodeOk`. Sometimes to update node state and make it failed you firstly need to send `Update return route` command than send `Has node failed` and check if the status now is `NodeFailed`. If so you can replace the node using the command `Replace Failed Node`, now the controller will start inclusion mode and status will be `Waiting`, now enable inclusion on your device to add it to the network by replacing the failed one.
