Networking

X Series amplifier platforms support linear daisy-chain,
star and loop network topologies; in a daisy-chained net-
work the pc with armonía pro audio Suite must always be
at one end of the chain.
Be aware that daisy-chaining does not guarantee reli-
ability in production environment, since any fault may yield
to network sectioning and loss of system control.
When efficiency and reliability are paramount, a redun-
dant network topology is advisable. in order to exploit the
Dante features, only star and open daisy-chain network
topology are allowed.

8 : 1.IP addressing

Factory default network settings are DHcp/autoip, in
order for the amplifier platform to self-configure when con-
nected to an existing LaN or pc. Fixed ip policy can also be
adopted and configured through armonía pro audio Suite.
if a DHcp server is not active within the network, the
amplifier platform initiates a stateless address auto-con-
figuration (i.e. Zero-configuration networking methodology
– Zeroconf): it self assigns a local numeric network ad-
dress (of the type 169.254.x.y – 172.31.*.* for the secondary
network if present – with a subnet mask 255.255.0.0) and
automatically distributes and resolves the hostnames of
networked devices. For setting a static ip address, please
refer to the armonía pro audio Suite user guide.

8 : 1.1. IP Addressing troubleshooting

When connecting the X Series to a network environment
it may happen that armonía pro audio Suite does not dis-
cover or import the amplifier.
usually this is a problem of ip addressing: both armonia
and the X Series must belong to the same subnet. if a DHcp
server is present on the network and a X Series amplifier
platform is in auTo ip, networking may become unstable.
As a rule of thumb, turn the DHCP server
on before connecting the amplifiers.
ip addressing of a X Series amplifier is established
during the bootstrap: when the X Series amplifier platform
discovers a DHcp server on the network during the startup,
it negotiates the networking parameters. if the X Series
amplifier platform does not reveal a DHcp server on the
network during the startup, it set itself in auTo ip mode.
8 : 2.Dante™ networking
The Dante equiped models of the X Series amplifier
platforms support Dante redundant networking via the two
ethercoN ports on the rear panel:
f primary/ETH1 is the primary network port;
f
f Secondary/ETH2 is the Secondary network port.
f
Dante connectivity is always supported on the primary/
ETH1 Gigabit Ethernet port; the Secondary/ETH2 Gigabit
Ethernet port offers continuity of operation when a parallel
redundant network is established.
in order to implement a Dante network, a computer run-
ning Dante controller have to be used. Dante controller is a
software application that manages devices on the network.
X series amplifier platforms are automatically discovered
and displayed in Dante controller with the default identifier
MODELNAME-SERIAL (e.g. X8-71520).
Dante networks will almost always require at least one
network switch. redundant infrastructures may require mul-
tiple switches. For maximum reliability, network switch shall:
f be rated for Gigabit Ethernet; f
f be Non-blocking;
f
f have quality of Service (qoS) with at least four queues; f
f have Diffserv (DScp) qoS with strict priority;
f
f have EEE (Energy efficient ethernet) switched off. f
For detailed information on setting up a switch, please
refer to the manufacturer's documentation.

8 : 2.1. Redundant network configuration

Dante redundancy can be set-up and used between
any supporting Dante-enabled audio equipment: it works by
using two completely independent and separate networks,
the primary Network and the Secondary Network.
To setup and use Dante redundancy, connect the
X Series amplifier platform and other redundant Dante-
enabled audio equipment using duplicate Gigabit switches
and Ethernet cables. connect your computer running Dante
Virtual Soundcard and Dante controller, and other non-
redundant Dante-enabled audio equipment to the primary
Network.
The primary and secondary networks MuST NoT be
interconnected at any point. Make sure any computer is set
to automatically configure its ip address.
