Model 5422A
DANTE INTERCOM AUDIO ENGINE
Selecting
Automatic
will cause the Model 5422A to use
DHCP or IPv4 link-local to establish the IP address
for accessing the Model 5422A’s management port.
With this setting, upon establishing a link to the Model
5422A’s management RJ45 jack the DHCP protocol
will request an IP address and related parameters.
If obtaining an IP address by way of a DHCP server
is not successful then the IPv4 link-local protocol will
be used. If the established IP address has the format
of 169.254.x.x then it was assigned using the IPv4
link-local.
Even if the management IP address was established
using link-local the DHCP protocol will stay active. The
Model 5422A’s firmware will continue to check for the
presence of a DHCP server. If one becomes avail-
able then an IP address will be requested and, when
obtained, will automatically be used, replacing the IP
address that was previously established by link-local.
The
Manual
setting allows the desired IP address
and related parameters for the management port 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 Manual IP
Address, Manual Subnet Mask, and Manual Gateway
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, and Manual Gateway fields.
Note that the front-panel display and associated push-
button switches can also be used to revise the Model
5422A’s management IP address configuration.
Note that to minimize the chance of losing access to
the Model 5422A’s management web server, restoring
the unit’s factory defaults will not change the currently
selected IP configuration choice.
Manual IP Address:
This field is grayed out and will
not show any text when the IP configuration mode is
selected for
Automatic
. When the IP configuration is
selected for
Manual
, this field will show the IP address
that is stored within the Model 5422A. This is the IP
address that is currently being used, or will be used at
the time of the next Ethernet management connection
reboot. This IP address allows access to the Model
5422A’s management web server and associated
menu webpages. It has nothing to do with the IP ad-
dresses associated with the primary and secondary
Dante Ethernet connections.
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
format (four octets separated by dots) the Submit
button must be pressed for the changes to be stored.
Restoring the Model 5422A to its default values will
not change the stored IP address. A system reboot
is required for a revised manual IP address to be uti
-
lized. Note that the front-panel display and associated
pushbutton switches can also be used to revise the
Model 5422A’s manual IP address (although it is less
convenient).
Manual Subnet Mask:
This field is grayed out when
the IP configuration mode is selected for
Automatic
.
This field will be display-only in this instance and
will show an IPv4 subnet mask value in dot-decimal
notation (four octets separated by dots) if the current
IP address and related network parameters were ob-
tained by way of DHCP. This is the subnet mask that
is being used by the unit’s management web server.
If the IP configuration mode is selected for
Automatic
and the current IP address was obtained by way of
link-local then a subnet mask address of 255.255.0.0
will be shown in this field.
When the IP configuration mode is selected for
Manual
the manual subnet mask field will not be grayed out. In
this situation, the stored subnet mask will be shown and
can be modified as desired to meet the requirements
of the application. The value shown is the subnet mask
that is currently in use, or will be used at the time of
the next Ethernet management connection reboot.
After entering the desired subnet mask value using
the standard dot-decimal notation format (four octets
separated by dots) 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. Note
that the front-panel display and associated pushbutton
switches can also be used to revise the Model 5422A’s
management subnet mask. Restoring the Model 5422A
to its default values will not change the stored manual
subnet mask value.
