Model 5401A
DANTE LEADER CLOCK
IP Address Configuration: This is a configurable
field with two choices: Automatic and Manual.
The selected configuration impacts how the Model
5401A obtains the IP address that is used for ac-
cessing the Model 5401A’s management web server
and associated menu webpages. This setting has no
impact on how the Model 5401A obtains IP addresses
for the primary and secondary Dante IP interfaces.
Selecting the Automatic setting causes the Model
5401A to use the DHCP or, if DHCP is not available,
the IPv4 link-local protocol to establish the IP ad-
dress for the Model 5401A’s management port. When
selected to use Automatic, upon establishing a con-
nection to the configured Model 5401A RJ45 jack the
DHCP protocol will request an IP address and related
parameters. If obtaining an IP address in this manner
is not successful then the IPv4 link-local protocol will
be used. (If an IP address has the format of 169.254.
x.x then it was assigned using IPv4 link-local.) Even
if the IP address was established using link-local
the DHCP protocol will remain active. In this case,
approximately every 30 seconds the Model 5401A’s
firmware will check for the presence of a DHCP server.
If one becomes available then an IP address will be
requested and, when obtained, will automatically re-
place the IP address that was previously established
by link-local.
The Manual setting allows the desired IP address
and related parameters to be manually entered. This
can be useful when a fixed addressing scheme has
been established. In this way, a static IP address can
be entered along with the other important network
parameters.
When selected for Automatic the fields for the
manual IP address, subnet mask value, and gate-
way IP address will be “grayed out” (will have a gray
background) to indicate that their values cannot be
manually changed. In this condition they are display-
only. Changing between Automatic and Manual and
vice-versa will not impact the values stored in the
manual IP address, manual subnet mask value, and
manual gateway IP address fields.
Note that to minimize the chance of losing access
to the management web server, restoring the Model
5401A’s default configuration values will not change
the currently selected IP address configuration
choice.
Manual IP Address: This field shows the stored IP
address associated with the management web server
when the manual mode has been selected for the IP
address configuration. This address has nothing to
do with the IP address utilized by the primary and
secondary Dante ports. When IP address configu-
ration is selected for Automatic this field is grayed
out and the value cannot be revised. Whenever the
IP address configuration is selected for Manual the
manual IP address can be modified as desired to meet
the requirements of the application. After entering an
IP address, using the standard dot-decimal notation,
the Submit button at the bottom of the webpage must
be pressed for the changes to be stored. A system
reboot is required for the revised manual IP address
to be utilized. The Reboot function is available on the
system webpage and the front panel. Restoring the
Model 5401A to its default values will not change the
stored manual IP address.
Manual Subnet Mask Value: This field shows the
stored subnet mask value associated with the man-
agement web server when the manual mode has been
selected for the IP address configuration. When IP
address configuration is selected for Automatic this
field is grayed out and the value cannot be revised.
When the IP address configuration is selected for
Manual this field will not be grayed out and the value
can be modified as desired to meet the requirements
of the application. After entering a revised subnet
mask value, using the standard dot-decimal notation
format, the Submit button must be pressed for the
change to be stored. A system reboot is required for
the revised subnet mask value to be utilized. Restor-
ing the Model 5401A’s default values will not change
the stored manual subnet mask value.
Manual Gateway: This field shows the stored gate-
way value associated with the management web
server when the manual mode has been selected
for the IP address configuration. When IP address
configuration is selected for Automatic the manual
gateway field is grayed out and the value cannot be
revised. When the IP address configuration is selected
for Manual this field will not be grayed out and the
value can be modified as desired. After entering a
revised gateway value, using dot-decimal notation,
