Given a Cat6509 w/ dual Sup720's running native IOS. A PA-POS-1OC3 was added to an existing FlexWAN card, but was not recognized. IOS on one Sup was upgraded to min. recommended version to recognize the POS card. POS Card was still not recognized. Would having the other Sup still on old code (only one rev older) cause this?
Have you reloaded the switch after copying the new files to the supervisor? Based on your output you are not running a supported IOS for the PA-POS-1OC3 card. It requires the 12.2(18)SXF and you have 12.2(17d)SXB currently running. According to the release notes neither of the IOS images you have running are supported. I would also recommend that both of your supervisors are running the same IOS versions. Here is a guide to upgrade the IOS on your switch.
