Model 5402
DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
be utilized. The management IP address will be associated
with a network connection made to either the Dante primary
or Dante secondary connections
If the network configuration is selected for ReMgmt
then the Dante primary IP address will be associated with
a connection made to the RJ45 jack labeled PRI on the
Model 5402’s back panel. Link Down will display if a
valid Ethernet connection has not been made. The Dante
secondary IP address will be associated with an Ethernet
connection made to the RJ45 jack labeled SEC on the
Model 5402’s back panel. Link Down will display if a valid
Ethernet connection has not been made with the Dante
secondary Ethernet interface. The management IP address
with be associated with a network connection made to
the Dante primary RJ45 jack located on the Model 5402’s
back panel.
If the Model 5402’s network configuration in Dante Control-
ler is selected for Switched or SMgmt ensure that
only one of the RJ45 jacks on the back panel is connected
to the LAN associated with the Dante devices. The other
RJ45 jack can be used to interconnect with another piece
of networked equipment. But having both the Model 5402’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 associated with the Dante primary,
Dante secondary, 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-decimal notion. A
gateway address is usually obtained using DHCP or by
way of a fixed (or static) stored value. When an IP ad-
dress 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
accessing 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 interface controller (NIC) devices used for the
Dante primary, Dante secondary, and management ports.
These are fixed hardware addresses assigned to Ethernet
ports. Each is unique among all Ethernet ports and cannot
be changed. The Model 5402 displays MAC addresses
as six groups of two hexadecimal digits, separated by
hyphens. No MAC address will be displayed if an Ethernet
interface has been disabled.
Switch Configuration:
This is a display-only field that
shows the Model 5402’s network configuration as deter-
mined by a setting in the Dante Controller application. The
term “Switch” refers to an Ethernet switching and routing
integrated circuit that is part of the Model 5402’s hardware.
How this integrated circuit is configured determines the how
the Model 5402’s three GigE Ethernet ports function. The
field will show Switched, Redundant, SMgmt, or
ReMgmt. 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 5402’s man-
agement 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 configurable field with
two choices: Automatic and Manual.
The selected configuration impacts how the Model 5402
obtains the IP address that is used for accessing the Model
5402’s management web server and associated menu
webpages. This setting has no impact on how the Model
5402 obtains IP addresses for the primary and secondary
Dante IP interfaces.
Selecting the Automatic setting causes the Model 5402 to
use the DHCP or, if DHCP is not available, the IPv4 link-lo-
cal protocol to establish the IP address for the Model 5402’s
management port. When selected to use Automatic, upon
establishing a connection to the configured Model 5402
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 pro-
tocol will remain active. In this case, approximately every
30 seconds the Model 5402’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 replace the IP address that was previously
established by link-local.
The Manual setting allows the desired IP address and re-
lated 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.
