NOTE
The Turbo Ring DIP Switches located on the
EDS-508A/505A’s outer casing can be used to
configure the EDS’s Turbo Ring protocols. (For
details on how to do this, refer to “Configuring Basic
Settings—Turbo Ring DIP Switch” section in this
manual.)
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 as shown in
