Turbo Ring DIP Switch
The
Turbo Ring DIP Switch
page allows users to disable the four DIP switches located on the
switch’s outer casing. When enabled, the DIP switches can be used to configure basic settings for
either the “Turbo Ring” protocol or “Turbo Ring V2” protocol. A complete description of the
settings is given below.
NOTE
The “Turbo Ring” protocol (recovery time < 300 ms) provides better network reliability and faster
recovery time for redundant ring topologies. The “Turbo Ring V2” protocol (recovery time < 20
ms), supports additional redundant ring architectures.
In this manual, we use the terminology
“Turbo Ring” ring
and
“Turbo Ring V2” ring
to
differentiate between rings configured for one or the other of these protocols.
For a detailed description of “Turbo Ring” and “Turbo Ring V2,” please refer to the
Using
Communication Redundancy
section later in this chapter.
