Phase 2 proceeds only if the self-test
determines that the CAB is isolated from the channel.Use the BARR/CHANNEL self-test to verify that the channel adapter and hardware are installed correctly and that they function properly. The procedures you follow are based on your connection type and hardware.

Use the BARR/CHANNEL self-test to verify that the channel adapter and CAB are installed correctly and that they function properly. To perform the self-test, you need the adapter test plug and the CAB terminator and test plugs. See the Hardware used for diagnostics topic for more information.
To test both the adapter and the CAB, you must run the self-test in two phases. Always test the adapter first so that if the adapter is at fault, you can avoid disconnecting the CAB from the mainframe channel.
Phase 1 of the self-test locates the adapter and then sends a data string of 256 characters. The adapter test plug returns the data through the receive side of the adapter, and the self-test verifies that the returned data matches the sent data.
Perform these steps to run Phase 1.
Connect the adapter cable to the adapter, then attach the test plug to the other end of the cable.
From the Diagnostics tab, select the adapter and then click Start.
In this phase, the self-test checks the connections from the adapter to the CAB through the Bus & Tag lines. The test sends a data string of 256 characters. Data sent through the Bus In is routed back through Bus Out by the Bus test plug, and data sent through Tag In is routed back through Tag Out by the Tag test plug. The self-test verifies that the returned data matches the sent data.
Follow these steps to run Phase 2.
If the CAB is online with the mainframe, remove it from service. Typically, you need to isolate the mainframe by turning off a channel switch or varying offline each channel device. These procedures differ from data center to data center. Follow the procedures required by the data center where the mainframe resides.
Phase 2 proceeds only if the self-test
determines that the CAB is isolated from the channel.
Make sure that the CAB power supply is connected to an electrical outlet and that the ENABLE/DISABLE switch is set to ENABLE. The test will not pass unless the CAB has power and is enabled.
Physically disconnect the Bus & Tag cables from the CAB. Then attach the terminator plugs and test plugs.
Always
connect Bus & Tag connectors black to white, never white to white
or black to black. The test will fail if you install the test plugs incorrectly.
Verify that the adapter is connected to the CAB. If you previously connected the adapter test plug to the adapter cable, you need to remove the adapter test plug and re-attach the cable to the CAB.
Verify that the red power LED on the CAB is on.
From the Diagnostics tab, select the adapter to test and then click Start to start the self-test.
If you encounter an error during this phase, contact Barr Technical Support.
Use the BARR/CHANNEL self-test to verify that the channel adapter and CHANNEL INTELLIGENCE cable are installed correctly and that they function properly. This test requires the supplied test plugs. See the Hardware used for diagnostics topic for more information.
To test both the adapter and the cable, you must run the self-test in two phases. Always test the adapter first so that if the adapter is at fault, you can avoid disconnecting the CHANNEL INTELLIGENCE cable from the mainframe channel.
Phase 1 of the self-test locates the adapter and then sends a data string of 256 characters. The adapter test plug returns the data through the receive side of the adapter, and the self-test verifies that the returned data matches the sent data.
Perform these steps to run Phase 1.
Attach the adapter test plug to the adapter. If you previously connected the cable to the adapter, you need to remove the cable and attach the adapter test plug to the adapter.
From the Diagnostics tab, select the adapter and then click Start.
In this phase, the self-test verifies the connections from the adapter to the CHANNEL INTELLIGENCE cable. The test sends a data string of 256 characters. Data sent through the Bus In is routed back through Bus Out by the Bus test plug, and data sent through Tag In is routed back through Tag Out by the Tag test plug. The self-test verifies that the returned data matches the sent data.
Follow these steps to run Phase 2.
If the CHANNEL INTELLIGENCE cable is online with the mainframe, remove it from service. Typically, you need to isolate the mainframe by turning off a channel switch or varying offline each channel device. These procedures differ from data center to data center. Follow the procedures required by the data center where the mainframe resides.
Phase 2 proceeds only if the self-test determines that the
CHANNEL INTELLIGENCE cable is isolated from the channel.
Attach the test plugs to the Bus & Tag In end of the cable, and the terminators to the Bus & Tag Out end of the cable.
The test will fail if you install the test plugs incorrectly.
Verify that the adapter is connected to the CHANNEL INTELLIGENCE cable. If you previously connected the adapter test plug to the adapter, you need to remove the adapter test plug and re-attach the cable to the adapter.
From the Diagnostics tab, select the adapter to test and then click Start to start the self-test.
If you encounter an error during this phase, contact Barr Technical Support.
Use the Barr ESCON self-test to verify that you installed the ESCON adapter correctly and that it functions properly. To perform the self test, you need the adapter loop plug and the coupler. See the Hardware used for diagnostics topic for more information.
Adapter diagnostics consist of a single self-test. Usually, you test the adapter and cable together. If the combined test fails, you can test the adapter separately, by running the self-test again with the loop plug installed on the adapter, so you can isolate any errors.
If the self-test detects an error it immediately stops and posts an error message. Correct the error, and then repeat the test to confirm that there are no additional errors.
To test both the adapter and the cable, you must run the self-test in two phases.
Phase 1 of the self-test locates the adapter and then sends a data string of 256 characters. The adapter loop plug receives the data and then returns the data through the receive side of the adapter. The self-test verifies that the returned data matches the sent data.
Perform these steps to run Phase 1.
If necessary, remove the protective cover from the adapter.
Attach the loopback plug to the adapter.
From the Diagnostics tab, select the adapter to test and then click Start.
In this phase, the self-test verifies the connections from the adapter to the far end of the fiber-optic cable. The test sends a data string of 256 characters. Data sent through the cable is routed back through the loop plug. The self-test verifies that the returned data matches the sent data.
Follow these steps to run Phase 2.
If necessary, remove the protective cover from the adapter.
Attach the fiber-optic cable to the adapter.
Remove the protective end pieces from the coupler.
Attach the coupler to the fiber-optic cable.
Attach the loop plug to the coupler.
From the Diagnostics tab, select the adapter to test and then click Start.
If you encounter an error during this phase, contact Barr Technical Support.
