Plans showing the floor layout and thelocal environment can be stored as background images. These allow the user to quicklyaccess specific network equipment − even without special knowledge of the IP structure.Finalised plans can then be exported and included in the documentation.4.1 ManagementTo use DMS functionality, one needs to switch over to the “DMS” tab. DMS is activated as afactory default. The Information page (Management/DMS Mode) shows how many devices havebeen recognised in the network, how many of these are on-line (active), resp. off-line (inactive).Off-line devices are those that are either turned off or have failed (defective terminal device) orare no longer available in the network (e.g. service laptop that is taken home by the installationtechnician after having completed the configuration).To be able to use DMS, one switch in the network must have been defined as the master. Thisswitch collects all the information and then passes this on to all the DMS -capable switches inthe network. The Controller IP field shows which switch (IP address) functions as the master.Determining the DMS Master:The mode „High” must be selected in the field „Controller Priority” of the switch, whichis supposed to be the master. The definition of the most powerful switch for this task isrecommended, as the DMS requires additional computing power. Further switches inthe network can be rated as „Mid” or „Low” depending on their power capability.The controller priority of a switch shall be set to „none” where a switch shall never be usedas a switch master.In case of a very high network load the DMS can be switched on at the switch with the lowestusage rate (and deactivated at the other switches), resp. Attention shall be paid as somefunctions can only be used in a limited way and this method is recommended in case of ahomogenous structure using barox switches.The master switch can be determined using the IP address in the line „Controller IP“.
