Hello, we are looking to upgrade our 4006 to a 4506 and were wondering if the ethernet line cards would work/be compatible if we took them out of the 4000 and dropped them in the 4500....we have:

3-10/100BaseTx Ethernet WS-X4148-RJ

and

1-10/100/1000 Ethernet WS-X4448-GB-RJ45

...so that's (3) WS-X4148-RJ cards, and (1) WS-X4448-GB-RJ45 card...any help would be greatly appreciated!
