2.4 SHDSL port 2 configuration
Once the SHDSL port 1 has been set up with the DIP switches SW3,
SW4, SW5 and once the network topology has been configured with the
DIP switches SW6 and SW7, the SHDSL port 2 configuration is
automatically set up by the product itself.
3 Testing the SHDSL connection and adjusting the data rate
Connect two SHDSL switches to the line and power them up as
explained at the “Installation” chapter.
Remark :
For test purpose on a desk, the line can be replaced by any Ethernet
straight cable.
The line led of the RJ45 SHDSL connector (it is the lower led) blinks
during the connection phase (45 seconds more or less) and lights on
when the connection is established.
Test the error rate by pinging remotely one of the devices connected to
the other XSRING.
If the Ping error rate is not close to 0%, decrease the data rate using
the DIP switches SW3, SW4, SW5.
4 Testing the Failsafe ring
The ring topology provides a much better availability :
if one line fails, the communication remains possible as previously
between all the devices.
If one SHDSL switch fails, the communication remains possible except
with the devices connected to the SHDSL switch in failure.
To check the failsafe ring runs properly,
