 Hot-swappable components in the 4500 : Supervisor, line cards, power supplies, and fan tray are hot-swappable

But best practice is to take back up, and do the change in change window. if any unforeseen may cause service interruption.

If the chassis only have a single supervisor card, powering down is necessary. 

If the chassis is dual-supervisor card, then it is not necessary.  Just make sure the new/replacement supervisor card is running the same IOS version as the active one. 

IMPORTANT:  Whether it is a single or dual-supervisor card, it is good practice to connect a console cable to the to the new/replacement line card and record the boot-up process in case troubleshooting is required.
