Hey guys, I've been having this ongoing issue with my x440-48p's.
I had a contractor come in a few weeks ago, who kept trying to connect a low-end PoE switch to one of my switchports - using one of the powered ports on his switch to uplink.
Immediately upon connecting, the port on my 48p would start blinking amber/green. When he moved it to another port, he knocked out that port too. Affected ports kept blinking amber/green until I rebooted the entire switch. Then they were fine.
Recently, another contractor came in while I was on vacation and did the same thing. I read them the riot act of course, but now I'm curious: Am I going to have to reboot my switches again, or is there a way to clear the error status for a port?
