Hi,
just to share about hot swap power supply...mine is out of topic a little, but the other day 1 of my servers had power supply unit (psu) problem and it is hot swap too. but when we plug out the damage psu and put back the psu (as asked by the engineer), the server suddenly shut down...
when the engineer came over, he even asked if the server can be shut down when he replaced the new psu..
so there is a need to be prepared for what can happen...

The 4506 switches do support OIR (on line insertion and removal) of PSUs. You just need to see how they are working together using the “show env power command”.
If they are running in redundant mode then you can replace 1 and the other will keep the chassis up.
If you are in combined mode and you have exceed the power consumption that 1 PSU could provide alone then system starts to shutdown linecards. I am guessing this is not right in your case or you would have mentioned it.
Cisco Switches do come with hot swappable power supplies, you can replace the defective one makes sure you are using this command
“power redundancy-mode redundant”
