[Troubleshooting help] HP Switch says my access point isn't connected to it (PoE), the AP is offline, but I can ping it, I can't SSH into it. Why would this be the case?

I figured it I can ping the AP, I should be able to find it on the switch via CIL, but I can't. If I restart the AP and it comes back online then it automatically appears on the switch.

Any idea why this would be the case? I have never seen this. If a piece of hardware is ping-able I expect to be able to find it connected to the switch. (Yes I had the right IP, I verified it when I pinged it and unplugged the AP. Yes I had the right MAC address).

TIA
