Hi Mike You can change the speed of the card using the OSA/SF interface from there you need to get a copy of the OAT and the configuration file for each one of the channel ids. In the configuration file you can change the speed of each port, after this you need to load the OAT and the configuration file to the OSA, now here you will have 2 options the first one is to only install the defintions you made but that do not put the changes in effect and the second one is to Activate the change this will interrup the current conections in the ports, unfortunatelly when you need to change something in the configuration file you need to vary off and on the channel. For the second question, yes the change take effect upon activation.
