After the Model 5401A has completed its
power-up sequences the unit will begin
operation. The eight front-panel LEDs will
reflect the real-time status of the unit’s major
functions. The front-panel display will allow
the viewing of over 20 menu pages show-
ing status and configuration conditions. In
addition, using the front-panel pushbutton
switches some of the unit’s configuration
settings can be revised as required.
The following paragraphs will detail the
operation of the front-panel LEDs.
Power LEDs
Two LEDs indicate the presence of incoming
AC mains and nominal 12 volts DC power.
They are labeled AC and DC and can light
green or red. When a source of AC mains
power is connected the AC LED will light
green. (This is actually in response to 12
volts DC that is being generated by the in-
ternally located AC mains input/12 volts DC
output power supply.) The LED labeled DC
will light green whenever a connected DC
source exceeds approximately 10 volts. The
DC LED will light red when the DC input is
between approximately 9 and 10 volts, indi-
cating a low-voltage condition. Once the DC
input is less than approximately 9 volts the
DC LED will not light and the Model 5401A
will no longer operate from the DC source.
Network LEDs
Three LEDs provide status indications re-
lated to the Model 5401A’s three Ethernet
network interfaces. Two of the LEDs are
associated with the Model 5401A’s Dante
primary and Dante secondary Ethernet
ports. They are labeled PRI and SEC. The
third LED, labeled MGMT, is associated with
the unit’s management Ethernet port. The
way in which the three Ethernet interfaces
and their associated status LEDs function
depend on the network configuration as
selected using the Dante Controller applica-
tion. The choices are Switched, Redundant,
Switched+Mgmt, and Redundant+Mgmt.
Switched 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 either the Dante
primary or the Dante secondary Ethernet port
and a link has been established. It will light
orange whenever a 100 Mb/s Ethernet con-
nection is present on either the Dante prima-
ry or the Dante secondary Ethernet port and
a link has been established.
SEC LED: The SEC LED will not light.
MGMT LED: When no Ethernet connection
is present on the management Ethernet port
the MGMT LED will not light. It will light green
whenever a Gigabit or 100 Mb/s Ethernet
signal is connected and a link has been
established.
Redundant 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 when-
ever a Gigabit Ethernet connection is pres-
ent on the Dante primary Ethernet port and a
link has been established. It will light orange
whenever a 100 Mb/s Ethernet connection is
present and a link has been established.
SEC LED: The SEC LED will light red when
no Ethernet connection is present on the
Dante secondary Ethernet port. It will light
green whenever a Gigabit Ethernet connec-
tion is present on the Dante secondary
Ethernet port and a link has been estab-
lished. It will light orange whenever a 100
Mb/s Ethernet connection is present and a
link has been established.
MGMT LED: When no Ethernet connection
is present on the management Ethernet port
the MGMT LED will not light. It will light green
