1 Time synchronisation in stand-alone operation (closed system) In the case of stand-alone operation, only Access components without a connection to other networks/Internet/time server are located within the network. The time set on the Access server supplies all Access end devices. In this case, the DHCP options 4 and 42 configured in the Access server point to the IP address of the Access server which acts as time server (NTP/ Time Server) for the Access end devices. Note: When installing the Access system on the customer’s own server hardware or virtualisation solution, the time server service (NTP/Time Server) in the server operating system must also be configured, otherwise a time server cannot be provided for the Access end devices.
