If a DHCP server for the assignment of IP addresses is active in the LAN, an unconfigured device disables its own DHCP server, switches to DHCP client mode and retrieves an IP address from the DHCP server in the LAN. However, this IP address is initially unknown and accessing the device depends on the name resolution:
-
If the LAN also has a DNS server for name resolution and this communicates the IP address/name assignment to the DHCP server, the device can be reached by entering its MAC address, e.g. 00a057xxxxxx.
Note: The MAC address on a sticker on the base of the device.
-
If there is no DNS server in the LAN, or if it is not linked to the DHCP server, the device cannot be reached via the name. In this case you have the following options to determine the IP address of the device:
- From another accessible device, use the WEBconfig function Show/search other devices, or alternatively the LANconfig function Find devices.
- Find the IP address assigned by DHCP to the device with the aid of suitable tools, and try to access the device directly using this IP address.
- Connect a computer to the device by means of the serial configuration interface and run a terminal program.
