10. Weed Ring Operates without IP Addresses Weed Ring Switches are addressed through their MAC addresses using low overhead primary Ethernet packets Every Ethernet device has a unique MAC address which is used by all Ethernet devices to route network packets By eliminating the IP layer from the ring management messages message size is reduced processing coding and decode steps are eliminated and response speed is therefore maximized By not requiring the assignment of an IP address Weed Ring Switches offer the great benefit of being able to be installed straight away without ever being connected to a laptop computer If a configuration change is required perhaps to fix a port or a specific speed or to enable a second independent ring the EOTec 2104 Switch Tools utility can identify the switches in the ring for you by using an Auto Find feature This feature finds the EOTec 2104 Ethernet Ring Switches and lists their MAC addresses automatically A wink feature included in the configuration tools identifies a switch for you by flashing the switch s OK LED Configuring Rings in Your Ring Switch It is essential to ensure that ring operation is enabled for the appropriate ports In other words you must specify which ports the EOTec 2104 Ethernet Ring Switch is going to use as ring ports all fiber ports are delivered pre configured as ring ports Never wire a ring switch in a ring topology without first configuring the switches ports as ring
