NOTE: The Turbo Ring DIP switches, located on top of the housing, alternatively can be used to 
configure the Turbo Ring protocols. 
If you use the web interface, console interface, or Telnet interface to enable the Turbo Ring DIP 
Switches, and then set DIP Switch 4 on the switch’s outer casing to the ON position, you will not be 
able to use the web interface, console interface, or Telnet interface to change the status of the DIP 
Switch. In this case, the Communication Redundancy settings will be grayed out in the web browser.
