Hi Guys, 

I encountered an issue with the display of FAN PS-2 as faulty. I have performed the reseat of power supply but the status is still displayed incorrectly.

Hi,

The output is correct. What you see below is for RPS and not internal PSUs.

Hi Reza,

My main concern is regarding the fan power supply 2. 

racvnpsw013#sh env all
FAN 1 is OK
FAN 2 is OK
FAN PS-1 is OK
FAN PS-2 is FAULTY

The fan and power supply is working as expected. However, it is still displayed as FAULTY. 

Do you recall any of the known bugs which is affecting this?

Hi,

Sorry, I did not see that in the output. Yes, I have seen this before in multiple 3850s. Upgrading to a different IOS version solved the problem.

I suspect the switch is hitting this bug as well, however, the version that the switch is running on is not listed in the bug documentation.
