Communications I/O adapter test
The I/O adapter test verifies correct operation of the communications I/O adapter. Because this test loads a diagnostic program into the card, you must vary off all lines from the communications I/O adapter before running the test.
Note the following when testing:
- A facsimile I/O processor
- The wrap connector cable must be attached from port A to port B on the I/O adapter card. This test sends a facsimile signal from port A to port B and back again.
- A wireless LAN adapter
- You do not need a wrap connector.
- The radio and RS-485 hardware
- Run the wireless echo back test. For details, see Wireless echo back test.
- A communications adapter that has two ports
- This is a two step test. The selected port on the on the two port adapter cable is tested first, then the I/O adapter card.
Test results:
- If this test completes successfully, the communications I/O adapter card is operating correctly.
- If this test fails, the I/O adapter card might be failing.
Notes:
- Verify that the wrap connector has the correct identifier (as indicated by the display prompt) and is properly installed.
- In some conditions, the associated I/O processor is the failing card. Select the I/O processor test option, if it is available on the display, to verify the I/O processor operation.
