Selecting this option causes the module to display all servers which match the order when viewing the "Manage Orders" page. This can be useful for testing.
Exclude servers that are currently running an installation
Activate this option if you don't want that WHMCS assign servers to new orders that are currently running a NOC-PS profile (i.e. an installation). This option is especially relevant if you also use the option "Start NOC-PS Profile on Terminate", as it ensures that the profile completes before WHMCS reassigns the server to a new order.
Exclude servers that are online
Enable this option to prevent a server that is turned on from being assigned to new orders. For example, if a server is used internally / temporary but is inadvertently assigned to a WHMCS product, the option prevents the server from being provisioned.
Keep NOC-PS Hostname
Enable this option to override the given hostname during ordering. If you want permanently keep the setted NOC-PS hostname, then also activate "Lock Hostname Field" at the Client Area Settings.
