We are installing 460-g2s (15.6.3.1 P 1-3) for one of our customers and have found about 40 or 50 ports that flash amber show delivering power and ready.
We are able to correct this issue but unplugging the patch cable waiting about 10 seconds for the light to go out and then patching the cable back in.
It is sort of a minor issue other than the fact that you have to be in the closet to identify or correct the problem.
Thanks
