Hi everyone!
We have currently a Cisco 6500 with 2 power supply of 3000w. We want to replace these PS for 2 new ones, which have higher wattage: 6000w.
Can we replace them without needing to turn the 6500 off?. I mean, What happens if we insert a 6000w PS and the switch is working with one 3000w PS?
Is it possible to do this replacement "on hot"?
And second, we also have a ws-x6708-10g-3c module. Can we insert this module "on hot"? Without needing to turn the Catalyst 6500 off?
Thanks a lot! and looking forward to an answer.

Hey,
Just adding a few things to this post. I am hoping you have 2PS 3000W units running in redundant mode (check with show power command) then perform the following:
1. Change the power redundancy mode to combined
2. Replace the PS units
3. When both the PS slots will have 6000W power supplies, configure the power redundancy mode to redundant again.
HTH.

Both support online insertion and removal so yes they are hot swappable, however I would make sure one power supply can keep the chassis up and running.

Thanks!.
But, i have one question. According to Cisco documentation, when I plug in the 6000w Power Supply, it disables the 3000w one. "With redundancy enabled, if you power up the system with two power supplies of unequal wattage, both power supplies come on line with a corresponding syslog message. The message indicates that the lower-wattage power supply will be disabled. If the active power supply fails, the lower-wattage power supply that was disabled comes on line"
Would this cause any interruption, or can we be certain that the switch will remain powered?

Depends on your setup the table should be able to help:

BTW, you didn't mention whether your 6500 chassis was the original or a later 6500E chassis. The former cannot take all the same power supplies as the latter - but off the top of my head, I don't recall what the maximum was for the original 6500 series.
