If there are more than two switches set as High-priority or no High-priority mode switch, the Switch with the longer system uptime will be selected as the DMS Controller switch. If two switches have same up time, the switch with the smaller MAC address will be assigned as the DMS Controller Switch. 2. You can set two switches to High Priority for Controller Switch redundancy. 3. The DMS Controller Switch should be put in a secure location such as a server room, with access/authority limited to IT staff. 4. The DMS Controller Switch is the center of IP / Event management to operate the DMS: a. When enabled DHCP Server mode in DMS network, the DMS Controller switch is responsible for assigning IP address for all devices. b. The DMS Controller Switch will Collect, Poll, and Sync DMS information, and act as the Event Notification control center to manage all device information. 27-4 DMS > DMS Mode Click on DMS Mode to display the DMS Information page: Parameter Descriptions: Mode : Enable or Disable the DMS function globally.
