To Reproduce Steps to reproduce the behavior:

1. We have Day 2 operations documentation for compute and object storage, but we don't have for network node https://docs.redhat.com/en/documentation/red_hat_openstack_services_on_openshift/18.0/html/maintaining_the_red_hat_openstack_services_on_openshift_deployment/assembly_rebooting-data-plane-nodes
2. Also on 17.1, it was not present, but the network node can be compared to a controlplane node on https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.1/html-single/installing_and_managing_red_hat_openstack_platform_with_director/index#proc_stopping-services-on-controller-nodes_shutting-down-and-starting-up-the-undercloud-and-overcloud
