This may be a stupid question. But does both 4003, 4006 and all 4500 series switches support the same line cards? Mainly asking about the ethernet line cards. Does the 4003 and 4006 support all the POE line cards (like WS-X4548-GB-RJ45V)? Does all the 4000/4500 series line cards support both CATOS and IOS? Because I see that the 4000 series only supports up to sup-IV. Is that right?
Thanks for your time and help.
