interconnections are made, the Model
5401A will perform its tasks without risk
of interruption due to conflicting resource
demands.
Flexible Networking
Capability
Using the Dante Controller application
program, the Model 5401A’s three Eth-
ernet ports can be selected to operate in
one of four modes: Switched, Redundant,
Switched+Mgmt, and Redundant+Mgmt.
This should allow virtually any desired
networking implementation to be easily
achieved.
By using the Switched or Redundant net-
work modes, separate network connections
will be maintained for Dante audio and
management purposes.
In the Switched mode a single Ethernet
connection to either of the Model 5401A’s
two Dante Ethernet ports will provide Dante
Leader clock functionality. The remain-
ing Dante Ethernet port will provide Dante
network “loop-through” capability and can
be used to interface with another piece
of Ethernet-connected equipment. The
management Ethernet port will be used to
access the Model 5401A’s monitoring and
configuration webpages.
In the Redundant mode two independent
Ethernet connections are made to the
Model 5401A’s two Dante Ethernet ports,
enabling Dante’s redundant networking
capability. Again, the management Ether-
net port will be used to access the Model
5401A’s monitoring and configuration
webpages.
In the Switched+Mgmt mode a single Ether-
net connection is used for both Dante Lead-
er clock functionality as well as providing
access to the Model 5401A’s management
webpages. The remaining Dante Ethernet
port will provide network “loop-through”
capability and can be used to interface
with another piece of Ethernet-connected
equipment.
In the Redundant+Mgmt mode two inde-
pendent Ethernet connections can be made
to the Model 5401A’s two Dante Ethernet
ports. This will enable Leader clock ca-
pability for applications that utilize Dante
redundancy. Access to the Model 5401A’s
management webpages will be made by
way of the Ethernet connection made to the
Dante primary Ethernet port.
Operating Power
The Model 5401A allows an AC mains
source of 100-240 V, 50/60 Hz to be directly
connected. It can also be DC powered us-
ing a 10-18 volt source that is connected via
a broadcast-standard 4-pin XLR connector.
If both AC and DC power sources are con-
nected the unit will be powered by the AC
mains supply. Only if the AC mains source
fails will appreciable power be drawn from
the DC source. This allows a source of DC,
typically an external power supply, to serve
in a backup capacity. With this arrangement
normal operation can continue even if AC
mains power is lost.
Future Capabilities
The Model 5401A was designed so that its
capabilities can be enhanced in the future.
A USB receptacle located on the unit’s
back panel, allows the three firmware files
(embedded software) to be updated us-
ing a USB flash drive. The Model 5401A’s
Dante firmware can be updated using one
of the unit’s Ethernet connections, helping
to ensure that the Dante capabilities remain
up to date. All software files and configura-
tion parameters are stored in non-volatile
memory.
