A 'power cycle' is a power off/power on of the AP.  In other words, someone or something removed electrical power from the AP, usually by unplugging it.

If this is powered via POE - check your switch
If this is powered via a local DC power supply, check your power outlet

Actually, whenever an AP loses contact with the ZD, it restarts. The default setting is 10 minutes I believe. So, what you need to figure out is why the AP is losing its connection with the ZD.

Update: If an AP loses connectivity, the message I see is "AP Restart: Network unreachable reboot", not the "power cycle" you see.

but there is no connection failure between when test ping with zd from ap. any idea?
