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.
