INSTALLATION
1.1
Unpack and Inspect the Equipment
The following components should be included:
1 SNE2000
1 power supply
If there is any visible damage, do not attempt to connect the device. Contact Customer Support at 1877-638-2638 (1-603-427-0600 for international customers) or support@nettonet.com.
1.2
Power Up the SNE2000
Plug the power supply into the Power Adapter port on the back of the SNE2000 and connect it to
your power source. Verify that the Power LED on the front of the SNE2000 is illuminated.
NOTE Upon start up, the Ethernet link will remain disabled (as indicated by solid illumination of the
Ethernet Rx, Tx, and Lnk LEDs) until the SDSL connection has been established.

Switches 1-3: SNE2000-P and SNE2000Q-P ONLY
Switches 1-3 on the SNE2000-P and SNE2000Q-P work in tandem with one another to provide
eight bandwidth options for the SDSL port. Distance capabilities listed in the following tables
assume the use of 26 American Wire Gauge (AWG) cable. Connections made with cable of a
lesser gauge (e.g., 24 AWG) will link up at greater distances. Your SNE2000 may not link up if
the cable is in poor condition or if the cable distance is greater than a particular bandwidth will
support; if link IS acheived under such conditions, traffic quality may be affected (e.g., packets
may be dropped).

*Adaptive mode allows the SNE2000-P to train up to the best possible speed
supported by the SNE2000-P, the remote modem to which it's connected, and the
copper cable pair connecting the two. The maximum reachable distance for an
SNE2000-P in Adaptive mode is 24,700 feet (at 144 kbps). The SNE2000Q-P does
not have Adaptive capability.
NOTE Bandwidth cannot be configured on the SNE2000-S or SNE2000Q-S; subscriber units
determine bandwidth via communication with their partner SDSL provider unit.

Ethernet Duplex Mode
Switch 4: SNE2000-P, SNE2000-S, SNE2000Q-P and SNE2000Q-S
The Ethernet link can be configured at either Full Duplex or Half Duplex mode. Although both
ends of the ETHERNET connection must have the same duplex mode configuration, it is not
necessary for partner providers and subscribers to be configured the same; duplex mode does
not apply to the SDSL link.

Full Duplex
1.3.2.1
Half Duplex Ethernet
Receive and transmit functions are mutually exclusive; data transmission occurs in only
one direction at a time. Packet collisions are not unusual.
1.3.2.2
Full Duplex Ethernet
The Ethernet line can receive and transmit simultaneously, effectively upping aggregate
bandwidth from 10 mbps to 20 mbps and preventing packet collisions.
1.4
Connect the SDSL Line
An SNE2000-S must be connected via an SDSL line to an SNE2000-P, a Mini DSLAM, a Micro
DSLAM or an IP DSLAM interface module. Likewise, an SNE2000Q-S must be connected via SDSL
line to an SNE2000Q-P, Mini DSLAM, Micro DSLAM or IP DSLAM interface module. Neither a
subscriber-to-subscriber nor a provider-to-provider connection will function.
Plug your SDSL cable into the SDSL RJ45 port on the back of the SNE2000. Verify the connection:
the SDSL Connection LED on the front of the SNE2000 will pulse green to indicate the connection is
established and operational.
Link up time between local and remote SDSL network extenders can vary from one to five minutes
depending on the quality, gauge and distance of the copper cable. If cable distance is greater than a

Plug the Ethernet cable into the Ethernet Connection RJ45 port on the back of the SNE2000. Verify
the connection: solid illumination of the Ethernet Connection Lnk LED on the front of the SNE2000
indicates a link has been established, IF an SDSL connection has already been made. If an SDSL
connection has NOT yet been made, the Ethernet link will remain disabled (as indicated by solid
illumination of the Ethernet Rx, Tx and Lnk LEDs) until the SDSL link has been established.

NOTE For most applications, the SNE2000 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 SNE2000, in order
to determine which type of cable is required.
