Upgrade Power Supply on Cat 6506 form 3000W to 6000W

[Stefan Sawluk]

Hello Folks.

I have to upgrade my power supplys in my cat 6506-E Switches from 3000W to 6000W. The 3000W PS are in redundancy mode. When i now change one 3000W to a 6000W do i have there downtime? 

Regards Stefan

Hey Stefan,

I suggest changing the power redundancy to combined before replacing the PS units. As in redundancy mode when chassis detects different wattage power supplies it error-disables the lower wattage PS unit. So it should be like this:

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.

RS.

Hello Rajeevsh. 

Thank you for your replay. I have read this, that the lower PS will disabled when i plug in a higher wattage PS. But its good to know that i have to change the mode. When i change this i don´t have downtime?
