Use this procedure to check that the Multiprotocol Communications Adapter required for an ACL exchange data link has been installed correctly.
Start
The system displays the SMIT Communications menu.
If the port status is not Available, the most likely cause is a poor connection between the adapter and its four-port box.
If you are unable to verify that the required port is Available, shut down AIX, power off the pSeries computer, and check the exchange data link's physical connections. Then repeat the verification procedure.
Next step: When you have verified the link, make sure that the tasklist.data file includes either an ACL or an SMSI process, as described in Checking the tasklist.data file.
