Hi We have ZD
5000 with the S/N:50:A7:33:24:D9:90, and the firmware: 126.96.36.199 build
148. The device is on for about 16 days now, and it has 261 APs
connected to it and working with no problem what so ever,until about 4
hours all the APs were disconnected at same time. I tried to restore the configuration but nothing workout, some of the APs connect again without any change from me. Is there any thing I can do to save time by configuring the APs manually
As you mentioned, some APs connect briefly. Eliminating the possibility of intermittent network connection, every once in awhile, the APs try to download the configuration from ZD over FTP. If there is a firewall in between the APs and the ZD that is blocking FTP access to ZD, then you will witness this exact behavior. Check the reason for disconnect. To further answer, if were to manually configure an AP, the problem will return when it will connect to ZD.
No, it should not but if it is happening frequently; you have to diagnose the issue, please have one of the AP directly connected to the ZD by powering it using external source.When the issue happens again please check this APs uptime; then that should give you the clue from then on you should be able to drive on to find the source for this problem.
Please check POE too just to be sure and rule it out
