Model 5401A
DANTE LEADER CLOCK
RJ45 LED Indicators
On the Model 5401A’s back panel there are three
RJ45 jacks that are provided for interfacing with the
unit’s three Ethernet ports. Two of the ports are typi-
cally used for Dante and the third for management
functions. The Ethernet ports are labeled Dante PRI,
Dante SEC, and MGMT. Associated with each RJ45
jack are two LEDs. One LED is labeled LINK and lights
orange when a GigE Ethernet connection has been
established with that specific port. The other LED is
labeled ACT and flashes green to indicate activity,
responding to Ethernet data traveling through the
specific port.
The Model 5401A’s three Ethernet ports, as a group,
can be configured, using the Dante Controller applica-
tion, to operate in one of four network configuration
modes: Switched, Redundant, SMgmt, and
ReMgmt. Details about the four network
configuration modes are provided in other sections
of this guide. The manner in which the LEDs associ-
ated with each RJ45 jack will light depends on the
network configuration. The following sections detail
the operation of the LEDs based on the specific net-
work configuration.
Switched Network Mode
Dante PRI RJ45 LEDs:
LINK (Orange): Off if no Ethernet signal is connected
or if a 100 Mb/s Ethernet signal is connected; lit if a
GigE Ethernet signal is connected.
ACT (Green): Off if no data traffic; flashes to show
data traffic.
Dante SEC RJ45 LEDs:
LINK (Orange): Off if no Ethernet signal is connected
or if a 100 Mb/s Ethernet signal is connected; lit if a
GigE Ethernet signal is connected.
ACT (Green): Off if no data traffic; flashes to show
data traffic.
MGMT RJ45 LEDs:
LINK (Orange): Off if no Ethernet signal is connected
or if a 100 Mb/s Ethernet signal is connected; lit if a
GigE Ethernet signal is connected.
ACT (Green): Off if no data traffic; flashes to show
data traffic.
Redundant Network Mode
Same as Switched.
SMgmt Network Mode
Dante PRI RJ45 LEDs:
LINK (Orange): Off if no Ethernet signal is connected
or if a 100 Mb/s Ethernet signal is connected; lit if a
GigE Ethernet signal is connected.
ACT (Green): Off if no data traffic; flashes to show
data traffic.
Dante SEC RJ45 LEDs:
LINK (Orange): Off if no Ethernet signal is connected
or if a 100 Mb/s Ethernet signal is connected; lit if a
GigE Ethernet signal is connected.
ACT (Green): Off if no data traffic; flashes to show
data traffic.
MGMT RJ45 LEDs:
LINK (Orange): Will not light.
ACT (Green): Will not light.
ReMgmt Network Mode
Same as SMgmt.
Front-Panel Display Page
Descriptions
The following sections provide information about the
Model 5401A’s front-panel menu pages. Additional
details can be found in the Model 5401A Configura-
tion section of this guide. Refer to Appendix D for the
menu structure diagram.
Row One
There are five display pages associated with the top
row which we’ll refer to as row one. They relate to the
timing status of the associated Dante network, the
Model 5401A’s selected internal timing, parameters
related to the sync input, and display of timing param-
eters that can be useful for factory troubleshooting.
Dante Sync Status Primary PTPv1: This menu
page will display the PTPv1 sync status for the Dante
primary interface. It will show Leader, Follower, Link
Down, or Error. The management webpages should
be utilized to observe the Model 5401A’s complete
sync status. Using the Home and Main webpages,
the status of the Dante primary and Dante second-
