LED Indicators
NOTE For most applications, the ENE3400 connects to a PC using a straight-through Ethernet cable
and to a hub or a switch using a crossover Ethernet cable.
For any other connection combinations you must verify the pinout of the Ethernet device to which you
are connecting the ENE3400 in order to determine which type of cable is required.

LED State Indication Additional Information
E3
Connection
Lnk
flashing
green E3 is operational The E3 connection has been established and traffic is
flowing.
solid green E3 link is established A connection exists but there is indication of a problem
with the E3 line.
no
illumination Loss of Synchronization (LOS)
The incoming connection to the
unit has been lost; no data is
being received.
If the outgoing connection from the unit has also been
lost then the unit's partner ENE3400 will have LOS as
well.
Note: When an ENE3400 has LOS, the Ethernet link
will be disabled and the Ethernet 100, Act and Lnk
LEDs will show solid illumination.
E3
Connection
Alm
no
illumination E3 is operational Note: If the E3 Lnk LED also remains unlit then the
unit has LOS.
solid amber Remote Alarm Indication
(RAI)
The outgoing connection from the
unit has been lost; no data is
being transmitted.
The unit's partner ENE3400 has lost its incoming
connection and has LOS.
Note: When an ENE3400 has RAI, the Ethernet link will
be disabled and the Ethernet 100, Act and Lnk LEDs
will show solid illumination.
pulsing
amber Alarm Indication Signal (AIS)
An indirect connection has been
lost; unit may no longer be
receiving data from its partner
ENE3400.
The unit's partner ENE3400 has lost a connection with
an intermediate device and has LOS or RAI.
Note: When an ENE3400 has AIS, the Ethernet link will
be disabled and the Ethernet 100, Act and Lnk LEDs
will show solid illumination.
Power solid green unit is operational If the Power LED is not illuminated, it is likely that the
ENE3400 is not receiving power and therefore none of
the LEDs will be illuminated.
