I have the problem that a Mainframe OSA-2 will not transmit data in any of 3 modules of WS-X6148-RJ45V in a CAT6513, running IOS 121-13.E6.

Just about any other Network card/OS (ie 3COM NIC or Intel/UNIX OS) work without issue.

A 10mb OSA-2 will work in a WS-X6516-GE-TX of the same CAT6513 but will not function in the WS-X6148-RJ45V modules.

The 10 and 100MB OSA will also function properly in a Cat 5500 and another 6509 (Hybrid OS) with the older cards (listed below).

Not Working 6513 - test 3 cards&multiple ports.

3* 48-port 10/100 mb RJ45 (WS-X6148-RJ45V)

working - Cat6509

10/100BaseTX Ethernet (WS-X6348-RJ-45)

Working - Cat5500

10/100BaseTX Ethernet WS-X5225R

10/100BaseTX Ethernet WS-X5234

10/100BaseTX Ethernet WS-X5224

Anyone know of a problem with the WS-X6148-RJ45V cards or a workaround for this connectivity?
