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 lights are combined link/act, not separate link act. left for upper side, right for lower side. 2 and 4 are blinking, 1 and 3 (the empty ports) are not.
This guy networks.
The lights are even labeled...
client had 2 near identical switches, one had LEDs on each port, one had LEDs all on top, I was looking at each port wondering why they weren't lighting up and thinking they were disabled in admin panel. took me a few minutes, I was an idiot that day.
By the authority conferred to me through the “ownership” of approximately 25cm^2 of Scottish highland from a well-intentioned holiday present, I’m invoking my right as a Lord to grant you a pass on that one.
It would take me a few minutes, too
As a Glencoe lord I support this.
The council has spoken.
They may go forth, unburdened.
So #5 is disconnected on the other end, right?
Yes, or the systems etc. Or the port is disabled if the switch has the ability.
Could've also just caught the photo in a flash of down activity depending. Still tho.
It's a gif and the LED is permanently off.
Port 4 is slightly pulled out, you can see the cable difference between 2and4. which I think is what OP was getting at.
It's probably touching just enough pins to keep active
It doesn’t seem to be, they look like different cables, look at the strain relief after the clear part, looks like a different pattern and shorter. They are probably both fully seated.
Hmm maybe I was wrong. Either way I think we can both agree this is everything just working normally...
Really? I've never seen that. In my experience, those labels are for the ports themselves, not the lights.
