devices. The other RJ45 jack can be used
to interconnect with another piece of net-
worked equipment. But having both the
Model 5401A’s Dante primary and Dante
secondary RJ45 jack routed to ports on the
same LAN will typically “crash” the network!
Subnet Mask Values: These three fields
will show the subnet mask values associ-
ated with the Dante primary, Dante second-
ary, and management ports. They will show
either Link Down or a subnet mask value.
The subnet mask value will be displayed in
dot-decimal notation. When the IP address
of the Dante primary or Dante secondary
interfaces have been obtained using link-
local the subnet mask value will always be
255.255.0.0.
Gateway Addresses: These three fields
will show the gateway address associated
with the Dante primary, Dante secondary,
and management ports. They will show
either Link Down, ---, or a value in dot-deci-
mal notion. A gateway address is usually
obtained using DHCP or by way of a fixed
(or static) stored value. When an IP address
has been obtained using link-local then
there will be no gateway address and --- will
display. A Dante interface will typically only
use a gateway address as a means of ac-
cessing an update server that’s is located
outside of the Dante network’s LAN.
MAC Addresses: Three display-only fields
will show the MAC (media access control)
addresses associated with the network in-
terface controller (NIC) devices used for the
Dante primary, Dante secondary, and man-
agement ports. These are fixed hardware
addresses assigned to Ethernet ports. Each
is unique among all Ethernet ports and can-
not be changed. The Model 5401A displays
MAC addresses as six groups of two hexa-
decimal digits, separated by hyphens. No
MAC address will be displayed if an Ether-
net interface has been disabled.
Switch Configuration: This is a display-
only field that shows the Model 5401A’s
network configuration as determined by
a setting in the Dante Controller applica-
tion. The term “Switch” refers to an Eth-
ernet switching and routing integrated
circuit that is part of the Model 5401A’s
hardware. How this integrated circuit is
configured determines the how the Model
5401A’s three GigE Ethernet ports function.
The field will show Switched, Redundant,
Switched+Mgmt, or Redundant+Mgmt. It
will also display Error in the unlikely event
that an error in the Dante interface circuit,
provided by a Brooklyn II module, has
occurred.
Management Interface
Configuration
There are four fields that relate to the Model
5401A’s management interface. They don’t
have any relation to the Dante primary and
Dante secondary IP addresses and their
associated network parameters.
IP Address Configuration: This is a con
-
figurable field with two choices: Automatic
and Manual.
The selected configuration impacts how the
Model 5401A obtains the IP address that is
used for accessing the Model 5401A’s man-
agement 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 address 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
