Once connections to the main primary and secondary networks
have been made, the unused ports can be used to create a daisy
chain to a nearby device. Simply connect the spare primary port
to the primary port of the nearby device. To maintain full
redundancy, the spare secondary port should also be connected
to the secondary port of the nearby device.
Figure 5 - "Redundant" mode with daisy chaining
*Note:
There are limitations using daisy chaining due to the
additional switch hops of a daisy chained switch/device in a
Dante™ network. While daisy chaining can certainly offer the
installer some benefits, careful consideration should be given as
to whether daisy chaining is suitable for any given application.
2.4.3 – Using on Standalone Network
The D32o supports both redundant mode and standalone mode
(indicated as “switched” mode in Dante™ Controller). If the D32o
is being used in a standalone network, running the D32o in either
“Redundant” or “Switched mode is perfectly acceptable and will
work so even though the D32o is setup in “Redundant” mode by
default, it can and will work happily in a standalone network
without changing anything. However, only the primary SFP port
or primary Ethernet port of the D32o may then be connected to a
standalone Dante™ network.
*Note:
Connecting either secondary port to a standalone Dante™
network while the D32o is still set in “Redundant” mode will cause
problems due to the IP address setup of the secondary ports
having completely different IP addresses. Therefore this should
be avoided.
Figure 6 - "Standalone" connection in “Redundant” mode
For full flexibility in a standalone network, the D32o should be
reconfigured to “Switched” mode. This is easily done by
connecting one of the primary ports to the standalone Dante™
network and then using Dante™ controller to switch the mode.
Figure 7 - "Standalone" connection in "Switched" mode
In “Switched” mode, the D32o reverts to using a single internal
network connection with a single IP address. The concept of
primary and secondary ports become irrelevant and all of the
ports (both SFP and RJ45) are connected together on the same
network essentially turning the D32o into a regular four port
network switch.
In this mode, the Dante™ network can be connected to any of the
four ports. Any unused ports may then be used to connect other
devices in a daisy chain. As the D32o is acting as a switch, other
devices connected to the D32o must then count the D32o as a
switch hop.
