Power Solid Green SNE2000 is
operational
If the Power LED is not
illuminated, it is unlikely the
SNE2000 is receiving power, in
which case none of the LEDs will
be illuminated:
Available
SDSL
Connection
Pulsing
Green*
SDSL connection
is established and
active
Traffic is flowing.
Solid Green Problematic SDSL
connection
A connection exists but there is
indication of a problem with the
SDSL line.

Ethernet
Collision
No
Illumination
Standard Either there is no traffic or traffic is
flowing without any collisions. If
there is no Ethernet connection,
the Ethernet Collision LED will
remain unlit by default.
An SNE2000 in Full Duplex mode
does not have collisions; the
Ethernet Collision LED is only
applicable in Half Duplex mode.
Flashing
Red
Packet collision(s) The Ethernet packet(s) will
automatically be retransmitted.
Solid Red Warning There is a potential traffic problem
over the Ethernet segment.
Ethernet Rx Flashing
Amber
Ethernet activity The SNE2000 is receiving data
from the Ethernet network.
Solid Amber Heavy Rx traffic The SNE2000 is receiving large
amounts of data from the Ethernet
network. A solid amber Ethernet
Rx LED can also signify a lost
SDSL connection.
No
Illumination
No activity Either there is no Ethernet link or a
link exists but there is no activity.
