Networking

X Series amplifier platforms support linear daisy-chain, star
and loop network topologies; in a daisy-chained network the PC
with ArmoníaPlus must always be at one end of the chain.
Be aware that daisy-chaining does not guarantee reliability
in production environment, since any fault may yield to network
sectioning and loss of system control.
When efficiency and reliability are paramount, a redundant
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 connected to
an existing LAN or PC. Fixed IP policy can also be adopted and
configured through ArmoníaPlus.
If a DHCP server is not active within the network, the ampli-
fier platform initiates a stateless address auto-configuration (i.e.
Zero-configuration networking methodology – Zeroconf): it self
assigns a local numeric network address (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 ArmoníaPlus user guide.
8 : 1.1. IP Addressing troubleshooting
When connecting the X Series to a network environment it
may happen that ArmoníaPlus does not discover 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:
X Primary/ETH1 is the Primary network port;
X
X Secondary/ETH2 is the Secondary network port.
X
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 running
Dante Controller have to be used. Dante Controller is a software
application that manages devices on the network. X series am-
plifier 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 multiple switches.
For maximum reliability, network switch shall:
f be Rated for Gigabit Ethernet;
X
f be Non-blocking;
X
f have Quality of Service (QoS) with at least four queues;
X
f have Diffserv (DSCP) QoS with strict priority;
X
f have EEE (Energy efficient ethernet) switched off.
X
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 sup-
porting 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 intercon-
nected at any point. Make sure any computer is set to automati-
cally configure its IP address.
