Testing an AT-AR041 or AT-AR042 NSM

The Test Facility is built into the AlliedWare operating system, and is the best method to verify the correct operation of the BRI interfaces on the AT-AR041 and AT-AR042 NSMs. Testing can be performed while the switch or router is operational, but any interfaces being tested are dedicated to the Test Facility.

For more information about the Test Facility, see the Test Facility chapter of the AlliedWare® Operating System Software Reference.

When testing BRI interfaces using the Test Facility, a loopback plug must be inserted into each interface being tested. The loopback plug connects the output pins on the interface to the input pins so that any data transmitted over the interface is looped back (hence loopback plug) and received at the same interface. Figure 7 on page 12 shows how to construct loopback plug to test the BRI interfaces.

To test a specific AT-AR041 or AT-AR042 interface, insert a BRI S/T loopback plug into the interface and enter the command:

enable test interface=brin

where n is the interface number.

To test all AT-AR041 or AT-AR042 interfaces at once, insert BRI S/T loopback plugs into all NSM BRI interfaces and enter the command:

enable test interface=expansion

Tests run for 4 minutes. Test status and results can be viewed at any time, using the command:

show test

which produces a display like that shown in Figure 8 on page 13.

The status of the tests for each interface will be shown in the right-most column of the output. For more information on the meanings of the other figures, see the Test Facility chapter of the AlliedWare® Operating System Software Reference for your switch or router.

If you are unsure about running the Test Facility, or have difficulty evaluating the results, contact your authorised Allied Telesis distributor or reseller.
