Model 5401A
DANTE LEADER CLOCK
at the end of this guide, for examples of how the Model
5401A’s three Ethernet interfaces might be utilized. It’s
difficult to conceive of a network environment that the
unit wouldn’t be able to effectively support.
Dante Port Connections
At least one 1000BASE-T (GigE) Ethernet connection
is required for Model 5401A Dante operation. It should
be connected to the primary RJ45 jack. A second
1000BASE-T (GigE) connection can be made to the
secondary RJ45 jack if Redundant Dante is desired.
For this functionality to be active the Model 5401A’s
network configuration must be set for the Redundant
or ReMgmt mode within the Dante Control-
ler software application. While technically 100BASE-
TX (100 Mb/s) Ethernet can also be used for these
Dante connections, it is not optimal. Additionally, it’s
important to note that 10BASE-T (10 Mb/s) Ethernet
connections are not sufficient.
When configured in Dante Controller for the Switched
or SMgmt modes the Model 5401A’s Dante
secondary Ethernet connection can also be used as
a “loop through” port such as would be provided by
an Ethernet switch. Using the Dante secondary port in
this manner for applications other than troubleshoot-
ing or “looping” to access the Model 5401A’s manage-
ment port is not recommended. It will function reliably
but “daisy chaining” Ethernet signals can limit flexibility
and present a failure point; it’s optimal if each Dante
Ethernet interface connects directly to a separate port
on an Ethernet switch.
Management Port Connection
If required by the needs of an application, the manage-
ment webpages can be accessed using an Ethernet
signal connected to the Model 5401A’s management
Ethernet port. This requires that the network mode in
Dante Controller be configured for Switched or Redun-
dant. It’s recommended that a 1000BASE-T (GigE)
connection be made but a 100BASE-TX (100 Mb/s)
connection is sufficient. (GigE will provide the best
performance and it’s assumed that all contemporary
applications will support it.)
Access to the Model 5401A’s management web-
pages can also be obtained using the same network
connection or connections that are being used for
Dante audio. This requires that the network mode in
Dante Controller be configured for SMgmt
or ReMgmt. Appendix B provides example
of how these network scenarios can easily be imple-
mented.
Connecting Power
The Model 5401A requires a source of AC mains or
nominal 12 volts DC for operation. Either source can
be connected with the same result. Both can also be
simultaneously connected if a redundant (backup)
power scheme is desired.
Connecting AC Mains Power
The Model 5401A can operate directly from AC mains
power of 100 to 240 volts, 50/60 Hz, 5 watts maxi-
mum. As a “universal mains input” device there are no
switches to set or jumpers to install. A 3-pin IEC 320
C14 inlet connector on the back panel mates with a
detachable mains cord set.
All units are supplied from the factory with an AC
mains cord that has a North-American (NEMA 5-
15L) standard plug on one end and an IEC 320 C13
connector on the other end. Units intended for use in
other destinations require that an appropriate mains
cord be obtained. The wire colors in the mains cord
should conform to the internationally recognized color
code and be terminated accordingly:
Connection
Wire Color
Neutral (N)
Light Blue
Line (L)
Brown
Earth/Ground (E)
Green/Yellow
Because the Model 5401A does not contain a power
on/off switch it will begin operation as soon as AC
mains power is connected.
Safety Warning: The Model 5401A does not con-
tain an AC mains disconnect switch. As such, the
AC mains cord plug serves as the disconnection
device. Safety considerations require that the plug
and associated inlet be easily accessible to allow
rapid disconnection of AC mains power should it
prove necessary.
Connecting DC Power
The Model 5401A can also operate from a source
of 10 to 18 volts DC. The current required from a 12
volts DC source is 0.5 ampere (500 milliamperes)
maximum. A 4-pin male XLR connector, located on the
unit’s back panel, is used to connect the source of DC.
