The Node module has one entity, the global node entity that crowns
    the hierarchy represented in the entity model described by the
    Digital Network Architecture. All other modules in DECnet-Plus are
    subordinate to the Node module.  When enabled, each node is visible
    to all other nodes on the network. Access to a node's entities must
    be made through the node.

    For Tru64 UNIX:

    To enable a node, use the command "enable node node-name" with
    either the local CMIP listener or the address watcher argument.
    For remote nodes with valid names, enabling the address watcher
    changes the node state from "off" (service interface disable) to
    "on" (service interface enabled). The CMIP listener must be enabled
    on that node. If the CMIP listener is not enabled, the node cannot
    accept management commands, and therefore cannot be turned on. For
    the node on which the director is executing, two enable directives
    may be necessary to accomplish the same action. The first enables the
    CMIP listener, and the second enables the address watcher, for
    example:

    ncl> enable node node-name function [=] {cmip listener}
                                            {address watcher}
