Turbo Ring DIP Switch Settings
The NI MES-3980 switches are plug-and-play managed redundant Ethernet
switches. The proprietary Turbo Ring protocol was developed by NI to provide
better network reliability and faster recovery time. The recovery time of the NI
Turbo Ring is less than 300 ms-compared to a 3- to 5-minute recovery time for
commercial switches, decreasing the possible loss caused by network failures
in an industrial setting. There are 4 Hardware DIP Switches for Turbo Ring on
the top panel of the NI MES-3980 that can be used to set up the Turbo Ring
easily within seconds.
NOTE
If you do not want to use a hardware DIP switch to set up the Turbo
Ring, you can use a web browser, Telnet, or console to disable this
function.
