whenever a Gigabit or 100 Mb/s Ethernet
connection is present and a link has been
established.
Switched+Mgmt Network Operation
PRI LED: The PRI LED will light red when
no Ethernet connection is present on the
Dante primary or Dante secondary Ethernet
ports. It will light green whenever a Gigabit
Ethernet connection is present on the Dante
primary or Dante secondary Ethernet ports
and a link has been established. It will light
orange whenever a 100 Mb/s Ethernet con-
nection is present on either Ethernet port
and a link has been established.
SEC LED: The SEC LED will not light.
MGMT LED: The MGMT LED will not light if
an Ethernet connection is not present on the
Dante primary or Dante secondary Ethernet
ports. It will light green whenever a Gigabit
or 100 Mb/s Ethernet connection is present
on either the Dante primary or Dante sec-
ondary Ethernet port and a link has been
established.
Redundant+Mgmt Network Operation
PRI LED: The PRI LED will light red when no
Ethernet connection is present on the Dante
primary Ethernet port. It will light green
whenever a Gigabit Ethernet connection is
present on the Dante primary Ethernet port
and a link has been established. It will light
orange whenever a 100 Mb/s Ethernet con-
nection is present on the Dante primary Eth-
ernet port and a link has been established.
SEC LED: The SEC LED will light red when
an Ethernet connection is not present on the
Dante secondary Ethernet port. It will light
green whenever a Gigabit Ethernet connec-
tion is present on the Dante secondary Eth-
ernet port and a link has been established.
It will light orange whenever a 100 Mb/s
Ethernet connection is present on the Dante
secondary Ethernet port and a link has been
established.
MGMT LED: The MGMT LED will not light
if an Ethernet connection is not present
on the Dante primary Ethernet port. It will
light green whenever a Gigabit or 100 Mb/s
Ethernet connection is present on the Dante
primary Ethernet port and a link has been
established.
Dante LEDs
Two LEDs are associated with the Model
5401A’s Dante interface. The system LED,
labeled SYS, and the synchronization LED,
labeled SYNC, will both light red as the
Model 5401A’s Dante interface starts to func-
tion and awaits connection and full operation
with one or two local area networks (LANs).
(Two networks are utilized only when Dante
redundancy is enabled.) The SYS LED will
light red to indicate that the Dante interface
is not ready to pass data to other devices.
It will blink red if there is an issue commu-
nicating with the internal Dante Brooklyn II
module. It will light green when the Dante
interface is operating normally and is ready
to pass Dante data.
The SYNC LED will light red to indicate that
the Model 5401A’s Dante interface has not
established timing synchronization. The
complete action of the SYNC LED will de-
pend on the Switch configuration as set
using the Dante Controller application. If
Switched or Switched+Mgmt has been se-
lected then the SYNC LED will slowly flash
green if this specific Model 5401A is serving
as the PTPv1 Leader clock for the associ-
ated Dante network. This will be a normal
situation as usually this unit will be provid-
ing the timing reference for all of the other
Dante devices. The SYNC LED slowly flash-
ing green can be misconstrued as an error
condition, but it is not. The SYNC LED slowly
flashing green will mimic the action that other
Dante devices will perform if they are acting
as the Leader clock.
