xNode Self Test Procedure
This document covers testing the input and outputs of an xNode using the built-in self-test.
- Device Under Test (DUT): xNode
- CAT5-6 Cables with RJ45 connectors at both sides for audio loopback test. (4 needed, see note)
- PC Computer: Running any telnet terminal (PuTTy, HyperTerminal, etc)
- A small network connecting the computer to the xNode. A regular or crossover Ethernet cable will do.
Reset to Factory Defaults
To ensure that there are no configuration issues that will cause false failures, it’s customary to factory reset the xNode before beginning. To do this, hold the two front panel buttons and power up the unit. Continue holding the buttons until the unit executes the factory restore. You can also do this via Telnet.
Reconfigure IP address
Set the IP address for NET 1 from the front panel as described in the quickstart guide. The xNode needs to be on the same subnet a the PC being used for the telnet session.
Connect with Telnet
Using an Ethernet connection to the DUT, log in with your telnet terminal emulator using the following parameters: 19200 Baud, 8 data bits, 1 stop bit, No parity, No flow control
Connect via telnet (port 23) to the IP address of the xNode.
The login username is “user” and there is no default password.
You should now see a “/home>” prompt.
Connect Loopback Test Cables
On the Analog, AES/EBU and Mic xNodes, connect the inputs of the xNode to the outputs in this manner:
1 <-----> 1
2 <-----> 2
3 <-----> 3
4 <-----> 4
Run Livewire Self Test
Enter the following command into your telnet session:
The first thing tested is a nonvolatile memory. You’ll see a PASS or FAIL.
Instructions will appear on the session telling you what to do next. If this is Analog or AES xNode, you’ll see instructions to connect loopback cables as we've discussed above.
The test will run while echoing data. When complete, it will show you a PASS or FAIL at the end.
