Hello, I have a 6509 and a 4500 switches, at the 6509 there is a WS-X6516-GB modules and at the 4500 there is a WS-X4148-GB module, I need to use one of them for a 7609, i can assume the WS-X6516-GB would work, but how about the WS-X4148-GB ? How can i verify if a card would work on another chassis ? Regards
