Hi everybody,
Today, a post with an odd problem. Few weeks ago, I was faced with 3 contiguous ethernet ports on a 5420M-48W-4YE switch which won't come up whereas PoE was delivering power. Admin state was up, but nothing. Making a test directly with a standard PC on same port was failing too: no ethernet connectivity. Switch was running since one year without problem. Rebooting it or even resetting it was unusefull. So I opened a case and RMA was initiated.
Ok. But yesterday, I was facing same issue with a new switch same model...and so I decided to ask you if someone encountered same problem or if anybody have an idea...
Regards.
