obtaining an IP address in this manner is
not successful then the IPv4 link-local proto-
col 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 ad-
dress 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 be-
comes available then an IP address will be
requested and, when obtained, will auto-
matically replace 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 estab-
lished. 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 gateway IP address will be “grayed
out” (will have a gray background) to indi-
cate 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 los-
ing access to the management web server,
restoring the Model 5401A’s default configu-
ration 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 prima-
ry and secondary Dante ports. When IP
address configuration is selected for Auto
-
matic this field is grayed out and the value
cannot be revised. Whenever the IP ad-
dress 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 sys-
tem 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 as-
sociated with the management web server
when the manual mode has been selected
for the IP address configuration. When IP
address configuration is selected for Auto-
matic 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 en-
tering 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. Restoring the Model 5401A’s
default values will not change the stored
manual subnet mask value.
Manual Gateway: This field shows the
stored gateway value associated with the
management web server when the manual
mode has been selected for the IP address
configuration. When IP address configura-
tion 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
