Model 5401A
DANTE LEADER CLOCK
ary interfaces, including their support for PTPv1 and
PTPv2, will be displayed.
Current Clock Source:
This menu page will display
which timing source is actively being used by the
Model 5401A’s circuitry. The possibilities are Internal,
Internal (Failover Active), Sync Input, Dante, Dante
(Failover Active), and ---. Should the text Failover Ac-
tive be present it will alternate on and off as a warning
of an abnormal condition. This would typically warrant
intervention.
Sync Input Type & Status:
This display page shows
two parameters. The top line will show the type of
input that has been configured for the sync input.
The possibilities are Word Clock, Video, or 10 MHz.
The bottom line will show the status of the sync input
circuitry. The possibilities are Locked, Unlocked,
Standby, and Idle.
Sync Input Termination:
This menu page will display
the status of a terminating impedance being applied
to the sync input BNC jack. The two possibilities are
Off and On.
Phase Detector Deviation (Factory Use):
This menu
page will display two numbers related to how well the
Model 5401A’s internal logic circuitry is “locking” to
an external timing reference. The information on this
menu page will only be relevant if the factory has been
contacted in regards to a technical issue.
Row Two
Row two has five front-panel menu pages that involve
the management IP address and related parameters.
Two are display-only and three allow changes to be
made.
Current Management IP Address:
This menu page
will show the IP address associated with the Model
5401A’s internal management web server. This ad-
dress can be assigned automatically using the DHCP
protocol or, if a DHCP server is not available, using
the IPv4 link-local protocol. (An IP address that has
the format of 169.254.x.x was assigned using IPv4
link-local.) The management IP address can also be
manually assigned with a fixed or static IP address. If
no Ethernet connection has been made the text Link
Down will be displayed.
If the Model 5401A’s network configuration in the
Dante Controller application is selected for Switched
or Redundant then this menu page will show the IP
address that’s associated with the connection made
to the Model 5401A’s management RJ45 jack.
If the Model 5401A’s network configuration in the
Dante Controller application is selected for
SMgmt then the IP address that is displayed
will be associated with a connection that is made to
either the Dante primary or Dante secondary Ethernet
interface.
If the network configuration in Dante Controller has
been selected for ReMgmt then the IP ad-
dress that is displayed will be associated with a con-
nection that is made to the Dante primary Ethernet
interface.
Current Management Subnet Mask Value:
This
menu page will show the subnet mask value setting
that is active for the management interface and as-
sociated web server. If the IP address and related
network parameters were obtained by way of DHCP
then this field will display an IPv4 subnet mask value
in dot-decimal notation. If the IP configuration mode
is selected for Automatic and the current IP address
was obtained by way of link-local, then 255.255.0.0
will show. It’s also possible that the subnet mask value
was manually entered as part of a fixed or static IP
address setting.
Management IP Configuration:
This menu page
allows the display and revision of the method that
the Model 5401A will use to obtain a management
IP address and related parameters. The choices are
Automatic and Manual. The selected configuration
impacts how the Model 5401A obtains the IP address
that is used for accessing the management web
server and associated menu webpages. This setting
has no impact on how the Model 5401A obtains IP
addresses for the Dante primary and Dante secondary
Ethernet interfaces.
An arrow icon will display in the upper-right corner of
this menu page. This indicates that the setting can
be changed. If the active method is not the desired
one, press the Enter pushbutton switch located on
the front panel. Use the left and right arrow buttons
to select the desired method. Then again press the
Enter button. The entry will be stored. To cause the
Model 5401A to use a new setting requires that the
unit be rebooted (restarted). This can be performed
