Can any one tell me if the switchport blades in the 4500 series (or 6500 series for that matter) are hot swappable? I have to add two more WS-X4248-RJ45V blades to an existing 4507 and I'm wondering if I'll need to shut that switch down (after hours) or if I can do that with the switch running (during hours). I see in the documentation where the power supplies are hot-swappable but it doesn't say anything about the blades so I am assuming no. Thanks for any infor provided.
I feel cisco 4500 switches support OIR (Online insertion and removal), so you can add cards to switch while it is running and there is no need to bring it down.
check this URL which tells that cisco 4500 supports high availability which enable hot swappable of line cards.
you can check using "show module" command once card is added to check if switch has detected the module or not.
As far as adding the card in cisco 4507R chassis, slot 1 and 2 is reserved for ONLY SUP card and as far as I know you can use slot 3-7 for any line cards.
HTH, rate if it does ....
