the switches all came with 9.14.2.2 and after a downgrade to 9.14.1.5 the uplink modules all get a link now
I have multiple of these modules and can only get one (out of 5!) to work. Here is the interface config i am usingno ip addressswitchportno shutdown If i plug any of the other four modules in the the same bay, they will not get a link light. The will show online in show sytem -- Module 1 --Status : onlineModule Type : S3148-10GE-2X10BaseT - 2-port 10GE 10BASE-T (XL)Num Ports : 2Hot Pluggable : yes   but no config will bring up a link light. I have set speeds to all available and negotion to all available. Surely i did not get 4 bad modules? Is there anything else i can do to troubleshoot?
