How to STOP logging message: Switch 1's power stack lost redundancy

%PLATFORM_STACKPOWER-4-REDUNDANCY_LOSS: Switch 1's power stack lost redundancy and is now operating in power sharing mode

I have a Cisco 3850 switch in a lab that only has one PSU installed. I am continuously getting the above logging message in the console.

Is there a command to stop this message without configuring a Logging Discriminator?

Hello,

is this switch part of a stack, or a standalone ? 

[G3000LEE]

Standalone

[Georg Pauwen]

Hello,

post the running config of the switch...

Hello,

take out this line:

--> switch 1 provision ws-c3850-48t

[G3000LEE]

Hi,

Sorry, it's taken so long to get back but only managed to get back into the office today.

Unfortunately, I get an error when I try to remove that line, see below.

LAB-CORE(config)#no switch 1 provision ws-c3850-48t

 Error: A switch is already physically present at this location

[G3000LEE]

Hi,

This command didn't resolve the issue.

[Leo Laohoo]

Look at the back of the switch.  Is the power stack cable attached?

[Georg Pauwen]

Hello,

this post has been around for a while, so I don't remember what steps you have already taken.

Have you already tried to power down the switch, remove the power supply, reinsert the power supply, and reboot the switch ?

[Deepak Kumar]

Hello, 

As I know this is a known bug with Stack switches but as it is standalone so suggested you can remove "no switch 1 provision ws-c3850-48t"

[Leo Laohoo]

What firmware is this switch running on?

[G3000LEE]

Hi guys,

The switch is in my office, and I'm not due back there for another week. I will update the post when I have tried the above.

Thanks
