3850 power supply b is not responding

[b_fourman]

This is a known bug with the 3850's and has been reported as a Bug (CSCue44402) Does anyone know if this issue been resolved?

We have upgraded to IOS XE 3.3.5, but are still experiencing the problem. IOS 3.7.1E has been released, but the Release Notes does not say that this bug was fixed. Anyone running version IOS 3.7.1 that has experienced this problem?

Hello,

The bug is fixed in 3.3.0 SE. So if you still see problem after upgrade to 3.3.5 , then it is a faulty power supply. Please RMA it.

Hope this helps.

Thanks Madhu...I have verified that the Power Supply is good, swaped it with a new one, I also noted that the LEDs on the back of the P/S were green before the P/S was swaped out. Interesting side note, if you reset the P/S the problem goes away, at least for a while.

Ok. Does it work fine on another 3850? 

If so replace the switch as it could be an issue on the chassis.

Thanks,

Madhu.

We are experiencing this issue as well on 2 of 4 3850 deployments on our campus.  Moving or re-seating PSU's fixes it for a bout a week or so but it comes back.  We are also running 3.3.5.  I find it hard to believe that 2 of 4 switches are bad and have the exact same symptoms as a known bug.  My guess is that is isn't completely flushed out in release 3.3.5.  I'm sure that there are more instances of this but since it appears to be a cosmetic issue many probably have not realized it.  Both Led's are green on the psu and it does seem to be supplying power.
