DANTE LEADER CLOCK
approximately 60 seconds, depending on which of
the three files are going to be updated. While files
are being loaded the green LED, located adjacent
to the USB receptacle, will flash slowly. Once the
entire loading process has completed the Model
5401A will reboot (restart) using the newly saved
firmware.
6. At this time the Model 5401A is functioning with the
newly loaded firmware and the USB flash drive can
be removed.
7. It’s a good idea to confirm that the desired Model
5401A’s Main MCU, Main FPGA, and Sync FPGA
firmware versions are loaded and operating as
expected. There are two methods for observing
the Model 5401A’s firmware version numbers. The
most direct is to use the front-panel display. Alter-
nately, the System webpage from the management
webpages can be utilized.
Note that no harm will occur if power is applied to the
Model 5401A that has a USB flash drive connected
that doesn’t have relevant files in its root folder. Upon
power up the green LED, located adjacent to the USB
receptacle, will flash on and off rapidly for a few sec-
onds to indicate that a valid file has not been found.
After this warning, normal operation using the unit’s
existing firmware will begin.
Dante Firmware Update
As previously discussed in this guide, the Model 5401A
implements Dante connectivity using the Brooklyn II
module from Audinate. The Dante Controller software
application can be used to determine the version of
the firmware (embedded software) that resides in the
Brooklyn II module. The System webpage provided by
the Model 5401A’s management web server can also
be used to identify the firmware version.
The firmware (embedded software) residing in the
Brooklyn II module can be updated using the Model
5401A’s Dante primary Ethernet port. Performing the
update process is easily accomplished using an au-
tomated method called Dante Updater that’s included
as part of the Dante Controller software application.
The Dante Controller application is available, free of
charge, from the Audinate website (audinate.com).
The latest Model 5401A firmware file, with an exten-
sion of .dnt, is available on the Studio Technologies’
website as well being part of Audinate’s product library
database. The latter allows the Dante Updater soft-
ware application that is included with Dante Controller
to automatically query and, if required, update the
Model 5401A’s Dante interface.
Restoring Model 5401A’s Default
Configuration Values
A command in the System Information webpage pro-
vided by the Model 5401A’s management web server
allows most of the configuration settings to be restored
to their default configuration values. This can be use-
ful but must be used with caution. Any customization
made to the Model 5401A’s configuration will be lost.
This can be offset in a positive way by returning the
Model 5401A to a known configuration, a point that
might aid in troubleshooting an issue. Refer to Ap-
pendix E for a list of the default values.
Lost User Name and/or Password
As is covered in detail in other sections of this guide,
gaining access to the Model 5401A’s configuration
menu webpages requires entering the correct user
name and password. If the default entries, both of
which are guest , are stored for use then they will
display on the Login menu webpage. Pressing the
Log In button on that webpage will then access the
Main configuration webpage. If either or both the user
name and the password have been configured to be
something other than guest (the default) then noth-
ing will show in the fields associated with the Login
menu webpage.
If knowledge of the stored user name and/or password
is “lost” then the Model 5401A includes a “back door”
to allow access. But as a security measure physical
access to the unit is required to utilize that access
method; there is no means to access the unit via an
Ethernet port without knowledge of the user name and
password. The exact process of accessing the Model
5401A’s configuration webpages without knowledge
of the user name and/or password is detailed in
Appendix G, located at the end of this guide.
