In the middle of a live VLAN readressing of a 200-node company, I encountered this gem. The ports just kept blinking on even after plugging out the cables. (HP aruba 24 port switch)
One turned off after a reboot.

The ports are numbered with arrows. Port one’s LED is on the left, port two is beneath port one and has its LED on the right. The two blinking above open ports are for even-numbered ports that are actively plugged in on the bottom row. I dunno why the LED for port five isn’t blinking; maybe the other end of the cable is connected to a device that is powered off.
